Vowel sounds like a short a€?oa€? as in the word a€?hot,a€? have low frequencies (250 to 1,000 Hz) and are usually easier to hear.
Consonants like a€?s,a€? a€?h,a€? and a€?f,a€? have higher frequencies (1,500 to 6,000 Hz) and are harder to hear. Sounds that are 120 dB or louder can be painful and can result in temporary or permanent hearing loss. Different groups and organizations use decibels to define the degree of hearing loss differently. Particular causes of hearing loss will be show up in the clinical audiogram in characteristic ways. Conductive hearing loss comes about when the transmission of sound to the inner ear is impaired, perhaps due to impacted ear wax (cerum), an ear infection (otitis media with effusion or OME), or calcification of the middle ear ossicles (otosclerosis).
It is often possible to treat conductive hearing loss by removing the cause of the physical obstruction. By far the most common cause of sensory neural hearing loss is damage to sensory hair cells in the cochlea.
Because our outer and middle ear transmits frequencies near 4 kHz very efficiently, hair cells that are tuned to frequencies near 4 kHz are particularly vulnerable to noise damage.


Even if we avoid exposure to very loud noise, the ear's outer hair cells may also simply wear out as we age, leading to age related hearing loss. There are many things that can cause damage to the auditory system, but the most common is noise damage. Please visit the NIH’s Interactive sound ruler for examples of various types of sounds and their hazard levels. Musicians work in a high decibel environment in which hearing loss, tinnitus, hyper-sensitivity to sound and sound distortion can result.  Traditional earplugs are not a good choice for the professional musician, as they reduce sound by muffling low-to-mid-range frequencies, which change the frequency spectrum of what they are hearing. Hunting requires the ability to hear very soft sounds, while still having a need for protecting the ear from the peak noise levels of a gun blast.
A person who has hearing within the normal range can hear sounds that have frequencies between 20 and 20,000 Hz.
Conductive hearing loss tends to a loss of sensitivity across the entire range of frequencies, most commonly in one ear only.
In this condition, high frequency outer hair cells tend to die off before low-frequency ones, possibly because the high frequency outer hair cells have to work harder if their job is to amplify acoustic vibrations on a cycle by cycle basis. Custom musicians earplugs are available that can protect the musician’s ears from loud sounds without distorting what they hear.


Loud, sudden noises (gunfire, industrial noises, woodworking, motorcycles, loud music, motorized lawn equipment, noisy hobbies and other noises louder than 90 db) are more damaging to hearing than regular and extended exposure to loud sounds over a period of time. Someone who cannot hear high-frequency sounds will have a hard time understanding speech and language. There are also a variety of in ear monitors that will enhance the music experience whether you are a serious musician or just a music aficionado. Not only can they choose from custom or over-the-counter earplugs or earmuffs, they can also choose protection devices that provide amplification while reducing the sounds of gunfire down to a safe level. Hearing protectors not properly fitted to the wearer’s ears do not effectively prevent damaging noises from penetrating the ear canal. Noise damage or age related hearing loss tends to produce characteristic deficits as shown in the audiograms here below. Unlike conductive hearing loss, which can often be cured, sensory-neural hearing loss is in most cases irreparable, and treatment will aim to make the best use of those auditory structures that remain in tact, perhaps by boosting sensitivity through a hearing aid, or, in severe cases, by trying to bypass dead sensory hair cells with cochlear or brainstem implants.
