Mild – cannot hear sounds below 26 to 40 dB. 3. Moderate – cannot hear sounds below 40 to 69 dB. 4. Severe – cannot hear sound…

The list below outlines different hearing loss thresholds as they are determined in relation to an individual with a normal hearing threshold. Mild hearing loss: 25 to 40 dB higher than normal. Moderate hearing loss: 40 to 55 dB higher than normal. Moderate-to-severe hearing loss: 55 to 70 dB higher than normal.

A sound’s volume is measured in decibels (dB), while its pitch is measured in hertz (Hz). Most healthy adults have an average hearing range of between 20 and 20,000 hertz. Sounds below 20 Hz are called infrasound, and those above 20,000 Hz are called ultrasound. You can counter hearing loss by wearing hearing aids in one or both ears.

It should be emphasized that this problem is not unique to the WHO hearing-impairment grading system, as many others yield similar classifications for age-related hearing loss (or other sloping audiometric configurations, such as occupational hearing loss). 4 The fundamental problem for age-related hearing loss, as shown in Figure 1, is that hearing is often well within the “normal” …

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. Keep a copy of your audiogram and other test results

However, hearing threshold of 25 dB HL or better is commonly considered normal hearing in adults, followed by mild (26–40 dB HL), moderate (41–55 dB HL), moderately severe (56–70 dB HL), severe (71–90 dB HL), and profound (>90 dB HL) hearing losses. 24 Fig. 11.2 shows age-related changes in hearing thresholds in different age-groups. Note that elderly males exhibit …
