What are the 5 levels of hearing?

There are 5 different levels of hearing loss: mild, moderate, moderately-severe, severe and profound. Mild Hearing Loss (26 dB- 40dB): this type of hearing loss is often associated with the inability to hear soft sounds.

How does the Rinne test work?

A Rinne test evaluates hearing loss by comparing air conduction to bone conduction. Air conduction hearing occurs through air near the ear, and it involves the ear canal and eardrum. Bone conduction hearing occurs through vibrations picked up by the ear’s specialized nervous system.

What is a good hearing test score in Hz?

Well, normal hearing is a person who can hear every sound frequency level, from 125 to 8,000 Hz, at zero to 25 dB. If you can hear all frequencies under 25 dB or higher, then you likely have perfectly normal hearing.

What is the most common hearing test?

Otoscopy testing This is one of the most common forms of testing for the causes of hearing loss. Your audiologist will take a close look at your eardrum and ear canal using a tool called an otoscope.

What do audiologists use to test hearing?

An audiometry test is when the audiologist uses different sounds to check how well you can hear. You will usually wear headphones, earphones or sometimes bone-conduction headband. The sensitivity of your hearing at different frequencies will be tested and the results are shown on a type of graph called an audiogram.

What is Rinne positive?

Rinne Positive: The patient is positive on that side (the ossicular chain is doing what it should be doing, acting as an amplifier). If the bone conduction through the mastoid process is heard louder than through the air, the patient is Rinne negative. This is always abnormal.

What is normal Rinne test?

Rinne test: Place the base of a struck tuning fork on the mastoid bone behind the ear. Have the patient indicate when sound is no longer heard. Move fork (held at base) beside ear and ask if now audible. In a normal test, AC > BC; patient can hear fork at ear.

What dB level is normal hearing?

Normal hearing range is from 0 dBHL (Decibel Hearing Level), which is the audiometric zero, to 20 dBHL. Any threshold, at any frequency, that is over 20 dBHL is identified as hearing loss. Though a ‘normal’ audible range for loudness is 0 – 180dB, anything over 85dB is considered damaging for our hearing.
