the mid-range of frequencies (1000-2000 Hz) and poorer at the lower and higher frequencies. For example, at 125 Hz the average sound pressure level required to achieve threshold in normal hearing individuals is about 45 dB SPL, while only 7 dB SPL at around 1500 Hz. To make hearing results easier to understand, rather than

Typical conversational speech occurs in the range of 30 to 50 dB. Nov 14, 2019 'Normal' hearing thresholds relate to speech-in-noise suggesting that the audiogram contains useful information for predicting speech understanding in perception that appears to be at the lower end of the Feb 5, 2021 The audiogram is used because it provides a convenient way to visualize hearing ability on a scale related to the “normal” range of hearing.

An adult is classified as having normal hearing ability if their responses indicate they heard noises between 0 and 25 dB across the frequency range. A child is considered to have hearing ability within normal limits if their responses are between 0 to 15 dB across the frequency range. Audiograms are set out with frequency in hertz (Hz) on the horizontal axis, most commonly on a logarithmic scale, and a linear dBHL scale on the vertical axis. For humans, normal hearing is between −10 dB (HL) and 15 dB (HL), although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing. Screening audiometry presents tones across the speech spectrum (500 to 4,000 Hz) at the upper limits of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children). 17 Results are
