Calculate the wavelengths in air at 20?C for sounds in the maximum range of human hearing. The speed of sound in air is 343 m/s. What is the wavelength of a 24-MHz ultrasonic wave?
(a) Calculate the wavelengths in air at 20 degrees celsius for sounds in the maximum range of human hearing, 20 HZ to 20,000 Hz. (b) What is the wavelength of a 14-MHz ultrasonic wave?
Calculate the wavelengths (m) of sounds in 30 degrees F air at the extremes of the audible frequency range of a young, normal-hearing human ear (i.e., highest and lowest frequency sounds we can hear). i know the highest is 20,000 hz and the lowest is 20 hz but I have no idea how to solve involving temperature.
Design a circuit which removes the entire audio frequency range (approximately 20 Hz to 20 kHz, for human hearing), but amplifies the signal voltage of all other frequencies by a factor of 15.
A person with normal hearing can hear sound waves that range in frequency from approximately 20 Hz to 20 kHz (1 kHz=1 kilohertz=103 Hz). Assuming the same medium, when compared to a 20 Hz sound wave, a 20 kHz sound wave has A. a shorter wavelength and a faster propagation speed. B. a shorter wavelength and a slower propagation speed. C. none of these. D. longer wavelength and a faster propagation speed. E. a longer wavelength and a slower propagation...
