What is the audible range for an average young person with unimpaired hearing?

1. Between 10-15,000 Hz

2. Between 20-20,000 Hz

3. Between 30-25,000 Hz

4. Between 40-18,000 Hz

The correct answer is: Between 20-20,000 Hz

The audible range for an average young person with unimpaired hearing is indeed between 20 Hz and 20,000 Hz. This range reflects the typical limits of human hearing, extending from the lowest frequency sounds that can be perceived (20 Hz) to the highest frequency sounds (20,000 Hz). Sounds below 20 Hz are referred to as infrasound, and those above 20,000 Hz are considered ultrasound, both of which are outside the capacity of human hearing. This understanding is fundamental in fields like audiology, sound engineering, and safety, where the impact of sound levels and frequency ranges is crucial for health and environmental considerations. Younger individuals generally have a wider hearing range compared to older adults, who may experience hearing loss at higher frequencies due to age-related factors. Therefore, recognizing the standard audible range reinforces the importance of maintaining hearing health, particularly in environments where exposure to loud sounds can be detrimental.
