Music is sound with a discrete structure. Noise is sound with a continuous structure. Music is composed of sounds with a fundamental frequency and overtones.

According to Wikipedia: Perfect pitch is a rare auditory phenomenon characterized by the ability of a person to identify or re-create a given musical note without the benefit of a reference tone. The thing to understand here is that a person with perfect pitch can associate all sounds with a note.

Most sounds are not what you would call a musical note, tone, or pitch. So in short, all sounds are made out of musical pitches, but not all sounds are musical pitches.

Auditory hair cells are specialized along the length of the cochlea to respond to specific sound frequencies. Each of our roughly 16,000 hair cells is dedicated to a narrow frequency range. These cells are ordered along the basilar membrane according to the frequencies they detect.

The higher the frequency at which a sound wave oscillates, the higher the resulting sound’s pitch you hear when that wave hits your eardrums. Your brain’s perception of pitch relies on how many of these compression changes your eardrum senses per second.

People of All ages without a hearing impairment should be able to hear the 8000hz. People under 50 should be able to hear the 12,000hz and people under 40, the 15,000hz. Under 30s should hear the 16,000hz, and the 17,000hz is receivable for those under 24. MORE: Test!

“What we observed is that older individuals don’t adapt as well to their sound environment.” This means that as we age, or ears and brain become more sensitive to sound, and years of wear and tear start to chip away at our ability to hear clearly.

Understanding high-frequency hearing loss. One of the most common types of hearing loss is known as high-frequency hearing loss. This means high-pitched sounds are harder to hear. It can affect anyone of any age, but is common in older adults with age-related hearing loss, as well as people exposed to loud noises.

Yes. Sound can absolutely kill you if it’s loud enough. The long answer requires looking at what sound really is. Sound is created by a pressure wave which vibrates particles as it travels in an accordion-like manner.

Most sound has been weaponized to disorient or anger opponents. In World War II, during the German siege of the Soviet city of Stalingrad in 1942, Soviet troops kept German forces awake at night by playing Argentine tangos through loudspeakers. In Vietnam, U.S. forces turned sound into psychological warfare.

Sound weapons would be like a bomb. You cannot control where the sound waves go off to. Though their are structures that could be made to minimize it. It is also theoretically possible to kill a person at just below 200 decibels of sound.

“Under certain conditions, sound waves cause the formation of small bubbles that rapidly implode and release an intense shock wave that produces enormous amounts of heat energy and a variety of highly active radicals, which can completely destroy adjacent material.”

Even a modest level of noise, over a long enough period of time (e.g. beeping garbage trucks, hair dryers, air conditioners), can cause damage to the brain networks that extract meaning from sound. Many of us don’t even realize our brains are being blunted and our thinking impeded by this invisible force.

The answer again, is YES. White noise machines benefit a baby by promoting sleep. However, it’s important to keep noise at a safe level for a baby and adults. If white noise machines produce sound above safe decibel levels, then they can be harmful.

Too high a white noise level above safe decibels has the potential to cause harm, inflicting more damage on babies’ ears than if they had not been exposed at all. It’s important white noise stays at a safe volume for babies as well as adults. Keep sound levels to that of a soft shower – around 65 dB.

10 Signs of Hearing Loss

1. Speech and other sounds seem muffled.
2. Difficulty hearing high-pitched sounds (e.g., birds, doorbell, telephone, alarm clock)
3. Difficulty understanding conversations when you are in a noisy place, such as a restaurant.
4. Difficulty understanding speech over the phone.

Deaf applicants, or those with profound hearing loss, should be able to qualify for disability benefits—either by meeting the SSA’s listing, or through a medical-vocational allowance. In addition, if you have good hearing in one ear, you won’t qualify for disability benefits.

Signs and symptoms of hearing loss may include:

• Muffling of speech and other sounds.
• Difficulty understanding words, especially against background noise or in a crowd.
• Trouble hearing consonants.
• Frequently asking others to speak more slowly, clearly and loudly.
• Needing to turn up the volume of the television or radio.

Find a quiet area to complete the hearing test. Choose if you prefer to use your device speakers or headphones. Headphones will provide you with more accurate results, and unlike device speakers, will test your right and left ears individually. Make sure the volume is on and set at a comfortable level.
