My son who is 5 yrs old just had a hearing screening test at school. I
recieved a letter stating that he needed futher evaluation.If someone
could help me understand the numbers I would be gratefull. Here are the
results: Right ear , 1000hz=25,2000hz=15,4000hz=20 Left
ear,1000hz=30,2000hz=15,4000hz=35. Tympanograms : Right
Type B Pv 0.6 Left Type B Pv 0.6 E-mails welcome.
Thanks , Jeff

Hi Jeff,
My students and I just did a screening of kindergarteners on Thursday. These
little folk are tested for signs of a hearing loss which can impede their
learning at such a young age. Many areas have adopted 20 dB (decibels) as
the minumum level which a child must pass to be considered normal hearing.
If a child fails at any frequency (pitch or tone) a more complete set of
decibel levels is obtained, if possible. The frequencies at which your son
was tested are a bit unusual, at least for the standard screening, which
involves the pitches 500 Hz, 1KHz and 2KHz.
Your son has a mild conductive hearing loss typically found in a condition
known as "fluid in the ears" or serous otitis media. It may worsen a bit, or
it may clear up, but he needs to see an otolaryngologist, who will look in
his ears and probably give him a decongestant and an antibiotic to help
clear his ears up. The tympanograms are type B, which also indicates that
condition. The eardrum doesn't move when air pressure in the ear canal is
increased and decreased. A normal eardrum will bulge slightly in and out as
the air pressure is changed. A type A tympanogram is the normal one, showing
the appropriate amount of movement with air pressure change, while a type C
indicates a floppy eardrum, which can indicate a breakage in the little
bones of the middle ear. The type B your son showed can mean fluid in the
ears, as I have said, or it can indicate a hole in the eardrum, which is
unlikely for your son, as his decibel levels are not severe enough to worry
too much about that. That is why you need to see a physician, so you will
know what the actual problem is.

Here's a magnificent step by step site to understand your, or rather
your son's, audiogram. I found it very helpful when we first started out
on this road too. Good Luck! But, be sure and follow up with a
specialist like mentioned. This is imperative!

Thanks, Lee Ann, for the tip on the "How to read your audiogram" website. I've
been wearing hearing aids for 20 years and I've just bought a Microlonk FM
system to augment them, and this website is by far the very best explanation of
the "numbers" that I have ever seen.
