The length of time a person is exposed to sound is called "duration of exposure." This refers to the amount of time a person is subjected to noise or sound levels that can potentially affect their hearing.
A standard threshold in hearing refers to the faintest sound that a person can detect at least 50% of the time across a range of frequencies. It is typically measured in decibels (dB) during a hearing test.
The absolute threshold of hearing is the lowest possible tone/decibel you could possibly hear. (This differs form person to person). The Differential Threshold is the point at which a person recognizes the decibel level has changed.Hope this answers your question, just learned this in psychology!
An energy chain in sound refers to the sequence of events that occur as sound energy travels from a sound source to a receiver (e.g., from a speaker to a listener). It involves the conversion of electrical energy to mechanical energy (sound waves) and ultimately to acoustic energy that is perceived by our ears.
Sound waves that travel to the ear for hearing are longitudinal waves.
Hearing aids are used to amplify sound, making it easier for a hearing impaired person to differentiate sounds and easier understand dialogue.
In a sense, But listening is more having a conversation and paying attention to what the person's saying. Hearing is just sound audible to you.

An aid can help a person hear better, but it won't return hearing to normal levels. Hearing aids boost all sounds, not just those the person wishes to hear. Especially when the source of sound is far away
Hearing Aids are used to amplify and *modulate sound for a partially deaf person. *Modulate - to adjust the pitch, tone or volume of sound.
A standard threshold in hearing refers to the faintest sound that a person can detect at least 50% of the time across a range of frequencies. It is typically measured in decibels (dB) during a hearing test.
When an object vibrates it produces disturbance in the medium and then the compressions and rarefactions produced travels through the medium to our ears from the vibrator and hence the sound is perceived.

The equipment is called "Long Range Acoustic Device" or LRAD. These are developed by American Technology Corp.

Hearing problems from a Sound Grenade are TEMPORARY; however if someone were to be REPEATEDLY exposed to Sound Grenades (many times), they would MOST LIKELY have PERMANENT HEARING PROBLEMS.
The screech or squeal you hear when hugging someone with a hearing aid is caused by sound waves. Hearing aids amplify sound to help the person hear better, and typically some of the sound waves escape out of the ear unnoticed. If you get too close to the hearing aid, however, instead of escaping out into the world, the sound waves are recycled back into the hearing aid. This is similar to putting a mic in front of a speaker. Screech! Most of the newer hearing aids have the technology to identify this sound and reduce it within microseconds, so they screech very little. Either way, if you are lucky enough to get a hug from someone, just disregard the sound, and enjoy the "squeeze" instead of the "screech"!
