Abstract:
In addition to registration of pure tone threshold audiometry in the standard frequency band and acoustic impedance audiometry, tone hearing thresholds were registered conventionally in extended frequency band (9-20 kHz) by air. A total of 103 otologically healthy volunteers (206 ears) aged 14 to 67 years participated in the trial. The results can serve as the standard in examination patients with pure-tone threshold audiometry by air in extended frequency band.

The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
Sound Intensity Level
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...
