Even one-time exposure to loud noises over 85 decibels can cause irreversible hearing loss. Your range of hearing shrinks as you age. Children can often hear sounds that the average adult is oblivious to.
Sudden sensorineural hearing loss that occurs typically in just one ear is known as sudden sensorineural deafness. If you experience this you should see a doctor right away. Humans can hear sounds in the frequency range between about 20 Hz to 20, Hz.
Babies may be able to hear frequencies above this range. For many adults, the limit of upper range for hearing is around 15, to 17, Hz. For reference, some species of bats can hear sounds as high as , Hz, or about 10 times higher than the human limit.
In most cases, high frequency hearing loss is irreversible. You can reduce your chances of developing high frequency hearing loss by dialing down the volume when using headphones, using earplugs when exposed to loud noises, and living an overall healthy lifestyle.

Of course, some people have a higher sensitivity to sound than others. While the majority of people respond negatively to excessively loud sounds or very sharp sounds, others find everyday sounds overwhelming too. Sensitivity to sound affects people with hearing loss and those with hearing function.
However, it is more common in people with certain types of hearing loss , such as sensorineural or age-related hearing loss. In addition to this, people who experience ear ringing or tinnitus may also have hypersensitive hearing. By understanding why you have hypersensitive hearing, you can take steps to resolve the issue and enhance your auditory experiences. People with normal hearing function will typically find very loud noises uncomfortable.
Noises within a frequency range of 2, to 5, Hz are known to be particularly difficult to listen to. There are two reasons for this. Firstly, our hearing function is damaged when we are exposed to loud noises. In fact, anything over 85 decibels could cause hearing loss. As we find these noises so uncomfortable to listen to, we are more likely to switch to a different environment or lower the volume, thus protecting our hearing function from exposure to the loud sounds.
Secondly, studies have shown that our brains respond differently to high pitched sounds, particularly those within a 2, to 5, Hz frequency range. As the amygdala is responsible for our emotional reactions, it may explain why these high-pitched noises cause us to experience a sense of discomfort, fear or even panic. People with normal hearing function can tolerate noises of up to decibels before they experience sensitivity.
Fortunately, hyperacusis can be treated by wearing hearing aids. The following is a greeting given in one of the 20 indigenous languages recognized by the State of Alaska. Sound is created when a vibrating source like a bell, motor or a stereo speaker sends sound waves through the air to your ear.
Every sound has two aspects: its pitch frequency and its loudness intensity. Intensity is determined by the volume control. Noise unwanted sound is usually made up of many frequencies.
The disturbing and harmful effects of noise depend both on the loudness and the frequency of the tones making up noise. Loudness is measured in units called decibels dB. A conversational voice is about 65 dB. A shout is 90 dB or greater.
Frequency is measured in units called Hertz Hz. The frequency of a locomotive horn is about Hz. The frequency of a table saw is about 4, Hz. Excessive noise can destroy the ability to hear, and may also put stress of other parts of the body, including the heart. For most effects of noise, there is no cure, so that prevention of excessive noise exposure is the only way to avoid health damage.
