Something in my system plays a digital alarm sound at 10 am every morning, and I don't know what's causing it. I figured out it's playing /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga, so the easiest workaround is probably to delete that file, but it's not exactly a satisfying solution.
Alessi Optic 02 B Alarm Clock: This now-discontinued model from Alessi was an example of high design being hampered by low-quality features. This clock was too audible to be a peaceful bedside companion, producing a tick-tock sound so loud that it bothered us even when we were in the next room. No doubt, the Italian space-age design is eye-catching, but having this clock near the bed made the passing of time a torturous, second-by-second affair. And we found its plastic construction flimsy, with tiny and difficult-to-set dial controls that had more in common with a cheap, drugstore alarm clock than something sold for many times the price.
As for the sound, alarms were likely based on the chiming of bells, which were used in a variety of settings, including communities and religious orders, De Lucca says. At some point, someone realized the process could be mechanized, which is what led to the first alarm clocks. Unfortunately, the sound of bells wasn't all that easy to replicate, he adds.
Alarm clocks generate noise to rouse you in a couple different ways. Some alarms, like old-school function ga4_link116() window.dataLayer.push(JSON.parse('"event":"default_event"')) analog clocks use two miniature bells positioned atop the clock with a small mallet that sways between them.
You can also try to make the most of your circadian rhythm to avoid alarm clocks. Instead of using an alarm to cue your mornings, try natural sunlight exposure or a function ga4_link120() window.dataLayer.push(JSON.parse('"event":"default_event"')) sunrise alarm. (We love the function ga4_link121() window.dataLayer.push(JSON.parse('"event":"default_event"')) Philips SmartSleep Wake-Up Light for its realistic simulation.) Getting sunlight in the morning will shift your circadian rhythm earlier. Sleeping in a dark room is the best practice. But if you can get away with it, consider leaving blinds cracked to allow sunlight in come morning, and let the rays gently wake you.
Our inspirations for the shape of Mudita Harmony were taken from Japanese and Scandinavian design traditions. Designed to be both simple and neutral, with a round shape that fits on the palm of your hand. The back of the alarm clock is inspired by nature - the holes in the speaker are uniquely placed to resemble the seeds of a sunflower.
Mudita Harmony also features a collection of nature sounds, prepared by a famous Polish nature sound artist, Marcin Dymiter. The collection of sounds features audio landscapes from Mudita's country of origin, Poland. You can choose to set them up as your alarm tone.
Every morning, A80S alarm clock will gradually wake you up by a red-tinted light which will slowly grow into soft white light, and you can cheerfully welcome the brand new day in a super relaxing mood.
Tired of the everyday tedious alarm sound? A80S alarm clock can give you more choices: Birdsong, Hawaii Wave, Streams, Beep, Wind bells, Chord and Piano. Getting up with the soft natural sound will let you enjoy a more refreshed morning. Also, if you are a radio fan, you can even preset FM radio and wake up to your favorite radio show.
It's like a standard alarm beep sound. The kind of thing you'd hear from a $5 digital alarm clock. It lasts for about 6 - 7 seconds maybe at most. Basically one full 'alarm clock' cycle. I don't know how else to describe it, unfortunately.

An alarm clock or alarm is a clock that is designed to alert an individual or group of people at a specified time. The primary function of these clocks is to awaken people from their night's sleep or short naps; they can sometimes be used for other reminders as well. Most alarm clocks make sounds; some make light or vibration. Some have sensors to identify when a person is in a light stage of sleep, in order to avoid waking someone who is deeply asleep, which causes tiredness, even if the person has had adequate sleep. To turn off the sound or light, a button or handle on the clock is pressed; most clocks automatically turn off the alarm if left unattended long enough. A classic analog alarm clock has an extra hand or inset dial that is used to show the time at which the alarm will ring. Alarm clock functions are also used in mobile phones, watches, and computers.
Many alarm clocks have radio receivers that can be set to start playing at specified times, and are known as clock radios. Additionally, some alarm clocks can set multiple alarms. A progressive alarm clock can have different alarms for different times (see next-generation alarms) and play music of the user's choice. Most modern televisions, computers, mobile phones and digital watches have alarm functions that automatically turn on or sound alerts at a specific time.
Traditional mechanical alarm clocks have one or two bells that ring by means of a mainspring that powers a gear to quickly move a hammer back and forth between the two bells or between the internal sides of a single bell. In some models, the metal cover at back of the clock itself also functions as the bell. In an electronically operated bell-type alarm clock, the bell is rung by an electromagnetic circuit with an armature that turns the circuit on and off repeatedly.[1][self-published source?]
Digital alarm clocks can make other noises. Simple battery-powered alarm clocks make a loud buzzing, ringing or beeping sound to wake a sleeper, while novelty alarm clocks can speak, laugh, sing, or play sounds from nature.[1]
User-settable mechanical alarm clocks date back at least to 15th-century Europe. These early alarm clocks had a ring of holes in the clock dial and were set by placing a pin in the appropriate hole.[9][10]
The first American alarm clock was created in 1787 by Levi Hutchins in Concord, New Hampshire. This device he made only for himself, however, and it only rang at 4 am, in order to wake him for his job.[11] The French inventor Antoine Redier was the first to patent an adjustable mechanical alarm clock, in 1847.[12]
Alarm clocks, like almost all other consumer goods in the United States, ceased production in the spring of 1942, as the factories which made them were converted over to war work during World War II, but they were one of the first consumer items to resume manufacture for civilian use, in November 1944.[13][14] By that time, a critical shortage of alarm clocks had developed due to older clocks wearing out or breaking down. Workers were late for, or missed completely, their scheduled shifts in jobs critical to the war effort.[14] In a pooling arrangement overseen by the Office of Price Administration, several clock companies were allowed to start producing new clocks, some of which were continuations of pre-war designs, and some of which were new designs, thus becoming among the first "postwar" consumer goods to be made, before the war had even ended.[15][16] The price of these "emergency" clocks was, however, still strictly regulated by the Office of Price Administration.[14]
A clock radio is an alarm clock and radio receiver integrated in one device.[18] The clock may turn on the radio at a designated time to wake the user, and usually includes a buzzer alarm. Typically, clock radios are placed on the bedside stand. Some models offer dual alarm for awakening at different times and "snooze", usually a large button on the top that silences the alarm and sets it to resume sounding a few minutes later.[19] Some clock radios also have a "sleep" timer, which turns the radio on for a set amount of time (usually around one hour). This is useful for people who like to fall asleep while listening to the radio.
Newer clock radios are available with other music sources such as iPod, iPhone, and/or audio CD. When the alarm is triggered, it can play a set radio station or the music from a selected music source to awaken the sleeper. Some models come with a dock for iPod/iPhone that also charges the device while it is docked. They can play AM/FM radio, iPod/iPhone or CD like a typical music player as well (without being triggered by the alarm function). A few popular models offer "nature sounds" like rain, forest, wind, sea, waterfall etc., in place of the buzzer.
Clock radios are powered by AC power from the wall socket. In the event of a power interruption, older electronic digital models used to reset the time to midnight (00:00) and lose alarm settings. This would cause failure to trigger the alarm even if the power is restored, such as in Home Alone 2: Lost in New York. Many newer clock radios feature a battery backup to maintain the time and alarm settings. Some advanced radio clocks (not to be confused with clocks with AM/FM radios) have a feature which sets the time automatically using signals from atomic clock-synced time signal radio stations such as WWV, making the clock accurate and immune to time reset due to power interruptions.
Alarm clock software programs have been developed for personal computers. There are Web-based alarm clocks, some of which may allow a virtually unlimited number of alarm times (i.e. Personal information manager) and personalized tones.[20] However, unlike mobile phone alarms, they have some limitations. They do not work when the computer is shut off or in sleep mode.[21]
Many modern mobile phones feature built-in alarm clocks that do not need the phone to be switched on for the alarm to ring off.[22] Some of these mobile phones feature the ability for the user to set the alarm's ringtone, and in some cases music can be downloaded to the phone and then chosen to play for waking.[23]
