- A sound wave has an intensity level of 121.3 dB in air. The density of air at 20.0°C is ρ = 1.20 kg/m3 (see Table 9.1). The speed of sound in air at 20.0°C is v = 343 m/s (see Table 12.1). What is the pressure amplitude of the wave?A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 7.69 104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect? ?mmA sound wave having a frequency of 266 Hz travels through air at 20 °C. The decibel level at a distance of 21.3 m from the source is measured to be 77.4 dB. What is the maximum displacement of air molecules at that location? Assume the density of air is 1.20 kg/m³ and that the source produces spherical wave fronts. Express the displacement as a number having the units of mirco meters. 1 micro meter = 1 x 10-6 m. For example, If your calculated answer were 1.873 x 10-7 m, your entry would be the number 0.187 7.13
