kuulmiskünnise

Kuulmiskünnis refers to the minimum intensity of a sound that a human ear can detect. It is typically measured in decibels (dB) and is frequency-dependent, meaning it varies depending on the pitch of the sound. For instance, the human ear is most sensitive to sounds in the range of 2,000 to 5,000 Hertz (Hz), where the kuulmiskünnis is lowest. At higher and lower frequencies, a greater sound intensity is required for detection.

The average kuulmiskünnis for young, healthy adults is often considered to be around 0 dB at 1,000 Hz, though this can vary. Factors such as age, exposure to loud noise, and certain medical conditions can elevate the kuulmiskünnis, leading to hearing loss. This means that individuals with a higher kuulmiskünnis will require louder sounds to hear them. The measurement of kuulmiskünnis is a fundamental aspect of audiology and is used in hearing tests to assess an individual's hearing ability. Understanding kuulmiskünnis is crucial for diagnosing and managing hearing impairments and for setting safe listening levels in various environments.
