Hello Readers.

I live in an apartment, and my neighbor directly below me
complains about my piano playing. I play at odd hours, because
I have a job, then I go to the gym, then I come home to play,
so I play late.

I have a digital piano, Yamaha GT1, and so I started to use
my head phones. He still complains about it. Still says
he can hear my piano. So I guess that the vibration or the
force bearing down on the keys is what he's complaining about.

Anyways, what can I put underneath my piano that would dampen
the vibrations that might be transmitted through the floor?

I'm thinking about getting a thick wrestling mat. Anyways,
your feedback would be greatly appreciated. Thanks!

Your wrestling mat idea might be more effective than the following,
which I used in an old house where I lived above another apartment. I
pasted a bunch of cork acoustic tiles to a large slab of cardboard,
then cut a rectangle of carpeting to cover it. Then I lifted the piano
onto the carpeting, which extended perhaps 4 inches beyond the piano
in front and on both sides. Because it was an acoustic piano and was
nearly against a wall, I also stuffed a few old comforters into the
open sections at the back of the piano, to keep sound from traveling
down the wall so easily. I think the piano was still really loud
downstairs. :-( But it was acoustic. Seems like headphones should
take the curse off a digital piano....

Make a new floor under your piano out of *stone* tiles!
The more heavy the mass, the more it will dampen the contact sound.
In addition: put rubber pads of 5 cm under the legs of your piano to damp
vibrations.

The best would be to install a 'floating' floor, on acoustical tiles covered
with floor parts like underlayment. Make sure you also close any small
openings in your floor with kit.

In other words, now that you gave initial cause for complaint by playing
with the speakers on, every noise you make will be the cue for some
response.

:-)

Seriously, it's likely that the neighbor is hearing either your pedaling
or the sound of your key strikes. I practice with headphones on my
Roland keyboard late at night after the kids have gone to bed, and my
son can still hear me from his room upstairs. The keyboard is in the
carpeted livingroom on the ground floor of a house with a solid slab
foundation, so it's definitely not from vibration conduction. The slope
of the vaulted ceiling and the thinness of his bedroom door at the top
of the stairs don't help, though, and probably exacerbate the problem.

The sound is much like very heavy raindrops hitting the roof and can be
bothersome.

I have been in this situation more than once. A distant neighbor
pounded on my door for playing my piano too loudly at 11:00 A.M in the
morning. Fine. Next time it was for playing too loudly at 1:30 in
the afternoon. Fine. A quick call to the city pointing out several
violations on his property stopped the complaints.

But I also changed my ways--more worried about the effect on the
immediate neighbor who didn't complain. But this is a loud acoustic
piano--a large typical Japanese upright in which volume is subsituted
for tone. To get a really soft tone out of it one has to resort to
using the practice pedal with the soft pedal--too much for some to
bear with the change in harmonics and feel. Or I can resort to my
digital piano.

But playing my digital piano with headphones in the living roomm, with
headphones, I also had complaints from my ..uhhhh......own house. I
was unaware the sound of the keys could actually bother anyone. I
moved the digital to another room where I can close the door and this
is not a problem.
Perhaps your digital piano is underneath the room where this person
sleeps. Moving the piano to another room might take care of the
problem--if you have the room. It sounds like your ceiling is very
thin. The sound of the keys is not loud compared to hammering or
something, but I guess it is loud enough in some situations.

Good luck.

Hello all.

Thanks for the suggestions. If you have more, please post them.
I have a question for you. What are acoustical tiles? Can I just
rest each foot of the piano on top of a 1-3 tiles, and that would work?

Right now, I cut out a workout mat (not a wrestling mat), and have a
couple of cork boards, and placed the feet on that. He still says
he can hear the piano.

Then I ask him, "Well what do you hear? Do you hear thuds? What?"
See I need to know what it is that he hears so I can try to find a good
solution.

But all he responds is, "I can just hear it."

So I'm beginning to think that he can't hear my piano, but just my feet
shuffling, or when I adjust the bench. Because if that were the case,
I'd tell him to go to hell, because it would be like asking me to not
pace in my own apartment. Or he may be a light sleeper.

If he told me that perhaps it was my pedaling, that would be good too,
then I can just practice pieces without the pedal, which is better than
nothing! I can practice with the pedal when I find the time during the
day.


I'm just annoyed that I have gone -I believe- more than half way by
buying a good headphones (Sennheiser -awesome), and putting dampening
material underneath my piano feet, and he hasn't -as far as I know- done
anything but complain.

If it might be practical, invite him up, show him your setup, point out
your headphones, pay a silent tune for him, and ask if he can point out
which sound he hears? (for the purpose of correcting it)

I wondered if you might be tapping your foot?

Since the neighbor is unable (or unwilling) to give you a specific
answer, I'd guess that he's just trying to be a jerk. If you are
using a digital piano, and using headphones, I'm not sure what exactly
he could hear, except maybe the pedaling and bench. I, too, used a
digital piano with pedals and with headphones in a second floor
apartment for nearly a year (before I moved) and never had a single
complaint from my downstairs neighbor.

I dunno. I would probably ask him again to be more specific about
what he's hearing, and like you said, that way you can address the
actual problem instead of driving yourself crazy trying a million
things to make him happy. The apartment is about YOUR happiness, too,
after all. And it's not like you're playing it 24-7. Perhaps you
could work out a time with him that he would not mind hearing the
noise, and practice then. Or ask him if you could come into his
apartment and listen while you have a friend stay in your apartment
and try various "experiments" with your piano (play the keys, with and
without headphones, depress the pedals, shift the bench, etc.) to help
you pinpoint it. Surely, if Neighbor Guy is truly disturbed by the
noise, he will cooperate in finding a solution. It may even help to
have the landlord or leasing office manager present during the
experiments as well.

Good luck and keep us posted on what happens.

This neighbor is starting to piss me off. Try this. Give him your telephone
number. Tell him the next time he hears you playing to call you immediately.
Wait a day or two before playing. Assuming he's home, if he doesn't call the
next time you start playing he's just looking for something to gripe about.
In which case, ignore him. If he does call, then there's some kind of
problem.

Hmm. I wonder if your keyboard is sending out RFI and he's picking you up in
his pacemaker, doorbell or electric toothbrush. Just joking, just joking.

As a corallary to this, you could do the phone thing here, and then move to
the piano, and instead of playing it simply sit there. If he calls, then
you can call him a jerk.

I just moved into a new place, bought the first grand piano I have had in a
long time, and have a noise issue with my next door neighbor. Up and down
can't hear me, but the side neighbor (I only have one) can, and she is
annoyed. The woman that lives above me is an architect, and she told me
that it is impossible to sound insulate these units. I am working out
practice times with the neighbor, and that will have to do.

I do have the advantage of being able to play my keyboard (which is far
enough away that she can't hear it even without headphones), but I do like
to play my wood piano now and again (I bought a piano, not furniture).

If we can't come to an accomodation on the time stuff, then I will have a
friend come over and play while I'm in her unit, and I'll see if I spend the
money to put soundproofing in or on the walls (big expensive project I want
to avoid).

Freddy, the solution is to have a friend of yours who plays the piano come
over to play your piano, while you go downstairs to hear whatever it is that
your neighbor hears. Then you will be in a better position to judge the
level of noise.

Or just tell the neighbor that a friend is about to play your piano, which,
of course, is not about to happen. You can pretend to stand by on your cell
phone to monitor the situation. When he says, "Ahah, there it is," you can
tell him that what he is really hearing is his ear wax congealing or
something.

After reading the many responding posts, I have not seen the following
addressed: your pedaling technique. I have often seen men with
long legs adapt a technique where they pedal with a large motion
from the knee. This caused stomping or, in extreme cases,
kicking the pedal. From an upper apartement this could be quite
noisy. Like another poster said, just walking across the floor in
places like this sounds like you're rearranging the furniture.

Explore the possibility that your pedal technique is the issue.
You should have the piano at a height and your bench at a
distance from the keyboard where you can rest your foot
on the pedal with your heel stationary on the floor. Then
the pedal is depressed with the ball of your foot and very
slight movement. In fact, a good position is to have both
feet resting on the two outer pedals and both heels on the
floor.

Then again, the guy could just be a jerk or an otherwise
nice person with tinnitus. It could be an electronic sound that
he can hear and not really realize what it is except that it occurs
when you're playing. People with severe tinnitus can react rather
oddly to those type noises (like the hum of a table lamp).

Freddy, from the steps you have taken, you've done more than enough.
Document to the landlord/building manager that you have taken measures
to limit the sound, including your inquiries at the police department
and city hall, the conversations you've had including affadavits from
the other, friendlier, neighbors and your friend who came along to check
the sound, pictures of your insulating mats, and a camcorder tape of
your headphone practice. (Maybe have someone near the camera give a nice
loud voiceover as you play silently, to compare the playing with human
conversation.) Perhaps even request a visit from the landlord/manager to
demonstrate what you've done.

Then forget about the putz.

Being kind to him may possibly have been interpreted as weakness, and
he's subliminally trying to get you to capitulate. So why not, tell him
to go to hell. You'll feel better.

You've done more than your share and you don't have to go on trying to
please this person. If he takes any action, you (and the landlord) can
whip out your documentation showing your good faith. But honestly, it
seems your neighbor is making more noise than you are.

I've known people to reject composers' entire opus on the basis of their
political ideology. Especially Wagner, which is pretty obvious, but
others also. What's interesting about it, is that you'd have to be
fairly educated on politics and history as well as music history in
order to know enough to reject some of these guys! Pfizner for being a
nazi? Schoenberg for being a communist? Odd that supposedly educated
people can also have closed minds.

When you say you play late, it probably means after midnight. Even
walking on the floor can irritate some people. It is always legal to
play the radio or tv at any hour at a moderate level. Doing so will
muffle/hide/ or eliminate the acoustical sounds of your playing I
suspect. In other words your neighbour needs to hear a legal sound such
as a low tv or radio where he has no grounds to complain.

You also may be surprised if you turn on a tape recorder such as your
tape deck and record (place a mike in the middle of the room on the
floor) your playing through a headset at 2:00 a.m. You may find you
are producing significant acoustical sounds you are not aware of such as
the heel of your foot on the floor moving about etc. as you play,
tapping the beat, etc. - at 2:00 a.m. This why a radio/tv playing in
the background is so important after 10:00 p.m. no matter what
activities you are involved in.

My all-time favourite is concrete blocks. They are a dream sound
barrier and dirt cheap.

You may wish to create a platform for you and your piano out of concrete
blocks - but I again, I don't think that is the problem. The problem is
no background sounds to muffle.

Place a thick layer of padding, of the type sometimes used to absorb
impacts from deadlift bars in gyms, on the floor. One has to do
calculations based on various aspects of the project to figure out an
exact depth, and one has to know what the engineering properties of
the padding are as they relate to this application - or, one can use
trial and error, and add padding until the result satisfies the
neighbors.

Assemble the piano onto the pad.

Position a 2 x 4 under each leg, which will distribute the weight and
vibration load into the pad over a larger area.

Weight applies a load both vertically, and horizontally......and the
depth of the padding provides depth for the load distribution, and
there should not be any significant sympathetic resonance to the piano
vibrations in that type of padding. The 2 x 4 s provide an
immediately very wide horizontal distribution of the load. In static
placement, the load will be evenly distributed from all points of the
2 x 4s, into the pad - an improvement over just having the piano legs
(or wheels) bear down into the pad (but, I'll let you do the equations
to find out how big the improvement is). The distribution level
increases, in exact proportions to the length of the 2 x 4s which you
obtain.

For what you are trying to do, you want to aim for length of
distribution and use 2 x 4s, and not use anything that would still
keep the distribution concentrated.

FYI, my father is presently the head mechanical engineer for an
Italian engineering firm, which has head quarters in the U.S.

Some decades ago, he worked on the jet engines for the SR-71, which
are designed to operate at three times the speed of sound, and also at
high altitudes.

Some persons, who just want to argue, may question I or my father's
expertise. Those persons don't deserve any consideration, and should
just be ignored.

Are you sure they're not hearing the key action? Whenever my father used to
practice with headphones on a digital piano, the sound of the action was
always astonishingly loud - and much more aggravating to listen to than
someone playing. Add to the fact that certain spots in an apartment can
make things sound like they're in the same room because of ventilation or
something.

I have some pads that are used in industrial settings to dampen the sound
and vibration of machinery. They are of rubber and look very much like small
waffles; unfortunately, I cannot find the specification sheet that came with
them which includes the manufacturer's name and describes their
sound-deadening properties.

Although I have had them for several years, I have never had to use them. My
present neighbors have a piano themselves, and are not bothered by my
playing.

Are the pads designed to dampen mechanical vibrations when in contact
with a vibrating object, or acoustic vibrations in the air?

If they dampen mechanical vibrations, are they compressed around
joints, intersections and piping (et c.), or do they work off of
bearing a weighted load?

If you can identify the manufacturer of the pad, I can look up the
specifications for that manufacturer's pads.

Is there any logo or trademark impressed anywhere on the pads?

I might be interested in buying these from you. But I want to find
out the design and material specifications, so that I can be sure they
are what is going to be needed, prior to making any commitment.

If you can email me a .jpg image of one of the pads, I can then email
the .jpg to my father, who will most likely be able to identify the
product for us - if not the manufacturer, then at least the nature of
the product, and what it is designed for.

Whether they are for sell or not, you might find it interesting to
know exactly what they are.

It is possible, of course, that they aren't all the same product.

I will look around the apartment for the manufacturer's specification sheet;
I came across it by accident recently, so I know it's here somewhere. It may
take a while.

They are made to bear the weight of machinery, and I suppose that the
waffle-like construction tends somehow to absorb some of the sound
vibrations. I think the specifications would explain their use better than I
can.

I worked for a research institute for 13 years, and one of our laboratories
did acoustical testing. When I contacted the head of that lab, he put me in
touch with the manufacturer of these pads, and the manufacturer sent me a
small number of them free of charge.

I found the specification sheet for the pads that are used to dampen sound
and vibration in industrial settings.

The pads are Mason Super W Pads, made by Mason Industries, Inc., with
locations in New York and Los Angeles.

The standard size consists of nine "waffles" by nine, and measures 18 in. by
18 in. by 3/4 in. (457 mm by 457 mm by 19 mm), and they can be cut into
individual "waffle"-shaped squares of 2 in. by 2 in. by 3/4 in. (51 mm by 51
mm by 19 mm).

The specifications say: "Pads can be used to reduce noise, high frequency
vibration and impact from typical machines...."

Although the pads are intended for industrial applications, I was told that
they could be used to muffle the sound that would otherwise be transmitted
downward by a piano.

The makers of Edwards string covers also sell a noise damping kit for pianos
which allegedly cuts the volume in half. I haven't tried them. Try
contacting them here for info:
