Hallásküszöbértéket

Hallásküszöbértéket, also known as the hearing threshold, is the minimum sound intensity that a person can perceive. It is typically measured in decibels (dB) and is an important indicator of a person's hearing sensitivity. The hearing threshold can vary depending on the frequency of the sound, with humans generally being most sensitive to sounds in the range of 2,000 to 5,000 Hz.

The normal hearing threshold for adults is generally considered to be around 0 dB, which is the threshold of hearing for a young adult with no hearing loss. However, this can vary depending on the individual and the specific frequency of the sound. For example, the hearing threshold for low-frequency sounds (below 1,000 Hz) is typically higher than for high-frequency sounds.

The hearing threshold can be affected by a variety of factors, including age, noise exposure, and certain medical conditions. For example, as people age, their hearing threshold tends to increase, making it more difficult for them to hear soft sounds. Prolonged exposure to loud noises can also damage the inner ear and increase the hearing threshold.

The hearing threshold is an important measure in audiology and is used to diagnose and monitor hearing loss. It is typically measured using a pure-tone audiogram, which involves playing a series of tones at different frequencies and intensities and asking the person to indicate when they can hear the tone. The results are then used to create a graph that shows the person's hearing threshold at different frequencies.
