Factors such as frequency, duration, and the sensitivity of our auditory system influence how loud a sound appears to us, even if its intensity remains constant.
Yes, even if two sounds have the same intensity, our perception of their loudness can vary due to differences in how our ears detect and interpret the sound.
Loudness measures the subjective perception of sound by the human ear, while intensity quantifies the actual physical energy of the sound wave.
Sounds with frequencies below 20 Hz are called infrasonic sound or infrasound. Humans generally cannot hear them. Give examples of animals that use infrasound for communication and the frequency they use.
Children under the age of five can hear frequencies up to 25 kHz, whereas adults typically cannot hear frequencies this high, as their ears become less sensitive to higher frequencies with age.
The audible range of sound frequencies for human beings extends from about 20 Hz to 20,000 Hz.
Examples of sound-absorbent materials used in auditoriums include compressed fibreboard, rough plaster, draperies, and specially selected seat materials that absorb sound effectively.
Sound-absorbent materials help in reducing reverberation by absorbing sound waves instead of reflecting them, thereby reducing the persistence and overlap of sound.
