In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to 15 dB at 250 Hz and 20 dB at 500 Hz. Hearing thresholds in the high pitches fall into the severe degree of hearing loss, as the threshold at 2000 Hz is 40 dB, 65 dB at 4000 Hz and 75 dB at 8000 Hz.

During a diagnostic hearing evaluation the threshold is measured at different frequencies (or Hertz, Hz) in each ear. The degree of hearing loss is expressed by the difference between a person’s threshold and the average threshold for people with normal sensitivity.

125 Hz - The low end of male voices. Due to restrictions in the dynamic range recorded by the .wav file format, the 125 Hz - 80 dBHL test cannot be performed online. 250 Hz - The low end of female voices.

The frequency range of a young person is about 20 to 20,000 hertz. The human ear is capable of hearing many of the sounds produced in nature, but certainly not all. Some low frequencies like a heart beat of 1 or 2 Hz can not be heard, just like sonar sounds produced by dolphins which are too high.

If you have trouble hearing any of the higher dbHL files, confirm these results by visiting an audiologist. Due to restrictions in the dynamic range recorded by the .wav file format, the 125 Hz - 80 dBHL test cannot be performed online. -5 dbHL: Outstanding hearing.

Even when I was a teen, prior to having been exposed to loud sound, I couldn't ever hear above 17khz. So I've lost 2.5khz of hearing in 15years, over that period of time I've been listening to 1000's of hours of music above 110db-C / 85db-A. I find this chart rather disturbing, as this is the average. and they say men lose it faster as well. According to this chart, music should start sounding significantly worse and worse for anyone over the age of 35. Compared to the average person in this chart, I've aged my hearing by 2 years beyond expected. Side Note: Oddly enough as I've continued to age and lose more and more hearing, via listening experience I've actually gained greater perception of speaker distortions than when I was younger with better hearing.

A sound with a low frequency will have a low pitch, such as a human's heartbeat. A sound with a high frequency will have a high pitch, such as a dog whistle. Humans cannot hear sounds of every frequency. The range of hearing for a healthy young person is 20 to 20,000 hertz. The hearing range of humans gets worse with age. People lose the ability to hear sounds of high frequency as they get older. The highest frequency that a normal middle-aged adult can hear is only 12-14 kilohertz.
