Kuulmisvajadus

Kuulmisvajadus refers to the level of sound intensity an individual needs to perceive speech or other auditory stimuli. It is a measure of hearing ability, often assessed in decibels (dB). A lower kuulmisvajadus indicates better hearing, meaning less sound intensity is required for detection. Conversely, a higher kuulmisvajadus suggests a hearing impairment, as a louder sound is necessary to hear. This concept is crucial in audiology for diagnosing and understanding the extent of hearing loss. Factors influencing kuulmisvajadus can include age, exposure to noise, genetics, and certain medical conditions. Quantifying kuulmisvajadus typically involves audiometric tests where individuals indicate the softest sounds they can hear at different frequencies. The results are plotted on an audiogram, providing a visual representation of a person's hearing profile. Understanding an individual's kuulmisvajadus helps in recommending appropriate hearing aids or other assistive listening devices to improve communication and quality of life. It is a fundamental parameter in determining the severity and type of hearing loss.
