A normal human body temperature can range from 33.2∘C to 38.2∘C. This range includes variations with gender, time of day, and where the measurement is taken. What is this range in ∘F? Express your answer in degrees Fahrenheit. Enter your answers numerically separated by a comma
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...
5. The threshold of human hearing at a frequency of 1.0 kHz is usually defined to be exactly 0 dB (for purposes of significant figures, consider this to be an exact, pure number). A research study shows that if exposed to 95 dB of a sound source for a long time, the threshold of hearing will shift upward to 32 dB. This accounts for why it is hard to hear normal conversations for some time after leaving a loud concert....
Mice communicate using ultra-sonic vocalizations (USVs), which contain high frequencies that are above the human hearing range. If you want to record USVs up to 80 kHz (1 kHz = 1,000 Hz), what is the minimum sampling rate (Fs)you should use? Hint: Use the Nyquist theorem. 40 kHz 160 kHz 80 kHz 80,000 Hz
