Most experts in agree that high-frequency noises range from about 2000 Hertz to around 800 Hertz. An average or mid-range frequency would be considered right at 1000 Hertz. Though, depending on the expert, these numbers can vary.
A magnitude of studies has come out through the science field, showing a high spike in people with high-frequency loss, with the increasing coming from teenagers, starting in the 1990’s. It is also suggested, that the spike isn’t from teens listening to music louder, and their environment being louder, but rather that they don’t report these occurrences, so medical professionals are not as able to help prevent, and reduce high-frequency loss.
What is High-Frequency Loss?
People who suffer from the loss of high-frequency noises, or sometimes referred to as partial deafness, are not able to hear high-frequency sounds, as the name suggests. These frequencies can be produced from saying the letters s, h, or f, for example.
High-frequency loss happens within the human body when the hair cells within the cochlea are either damaged or missing. This is similar to sensorineural hearing loss, as well.
The cochlea, interprets low-frequency sounds in the top part, while high-frequency sounds are perceived within the bottom portion. Because of this, people are more subjective to losing their ability to hear frequencies, before the loss of low ones.
Causes of High-Frequency Loss
When you are diagnosed with the high-frequency loss, there can be several reasons, with more than loud and high pitched noise being the culprit. Ageing, which is unstoppable, is the most common cause, as well as, things like chemotherapy drugs (ototoxicity), genetics, and various other diseases and syndromes.
Diabetes is also suspected of being a possible contributor, but that is still in question.
Knowing the causes and how high-frequency hearing loss happens can significantly reduce the chances of it affecting you. Sometimes, though, there is not much you can do about it, as ageing and genetic have a pretty big part to play in all of this.
Symptoms and Effects of High-Frequency Loss
Think you might have high-frequency hearing loss, but you’re not exactly sure? There are a couple of signs having this problem like if you have problem with understanding people over the phone, not being able to hear door bells, and bird noises like you used to be able to, not being able to hear females as good as you can hear male voices, having conversations with multiple people, and when some speech sounds muffled and heard of hearing.
There are not too many ways to prevent high-frequency. The best way to lessen your chances would obviously be to listen to all audio at lower and safer volume. There is a possible way to correct high-frequency hearing loss, however.
This can be done with the use of Electric Acoustic Stimulation (EAS). EAS is a trial implant that takes electric stimulation, along with acoustic amplification, and combines them. This is ideal if you have a high-frequency hearing loss because it assists with reproducing high-frequency sounds with the electric stimulation, while acoustic amplification supports low frequencies.
