Sound Attenuation with Laminated Safety Glass
The young human ear hears sound in a range from 10 to 18000 Hz, while the range for old people is only about 100 to 10000 Hz (old people often need hearing aids). Frequencies below 1000 Hz are deep, rumbling sounds, e.g. of car, ship or aircraft engines. All tones between 1000 and 8000 Hz are contained in normal road traffic noise – this is the medium frequency range. Sounds from 8000 to 18000 Hz are high frequency or high-pitched, e.g. the piping of a whistle or high pitched wind instruments in music.Know more
