Approximately a third of people with normal hearing have ears that continuously emit a low-intensity sound outward through the car canal. A person with such spontaneous otoacoustic emission is rarely aware of the sound, except perhaps in a noise-free environment, but occasionally the emission is loud enough to be heard by someone else nearby. In one observation, the sound wave had a frequency of 1665 Hz and a pressure amplitude of 1.13 × 10−3 Pa. What were (a) the displacement amplitude and (b) the intensity of the wave emitted by the ear?

- Some studies suggest that the upper frequency limit of hearing is determined by the diameter of the eardrum. The wavelength of the sound wave and the diameter of the eardrum are approximately equal at this upper limit. If the relationship holds exactly, what is the diameter of the eardrum of a person capable of hearing 20 000 Hz?

Calculate the displacement amplitude of the wave at a frequency of 10.0 kHz.arrow_forwardThe area of a typical eardrum is about 5.00 X 10-5 m2.

- Sound is detected when a sound wave causes the tympanic membrane (the ear drum) to vibrate. Typically, the diameter of this membrane is about 8.4 mm in humans. A) how much energy is delivered to the eardrum each second when someone whispers (20 dB) into your ear? B) to comprehend how sensitive the ear is to very small amounts of energy, calculate how fast a typical 2.0 mg mosquito would have to fly (in mm/s) to have this amount of kinetic energy.arrow_forwardThe area of a typical eardrum is about 5.0x10−5 m2. What is the sound power (energy per second) incident on the eardrum at the threshold of hearing? What is the sound power (energy per second) incident on the eardrum at the threshold for pain?arrow_forwardYour experiments on a particular insulator indicate that a 20 C the average speed of sound in the insulator is Vi = 7250 m/s Its bulk modulus is Bi = 450 GPa. Experimental results from your colleague show that a certain metal alloy has a density of rom = 7500 kg/m3 and a bulk modulus of Bm = 180 Gpa. The density of the insulator roi = 8561 kg/m3.

- Some studies suggest that the upper frequency limit of hearing is determined by the diameter of the eardrum. The diameter of the eardrum is approximately equal to half the wavelength of the sound wave at this upper limit. If the relationship holds exactly, what is the diameter of the eardrum of a person capable of hearing 20 000 Hz? (Assume a body temperature of 37.0°C.)arrow_forwardA sound wave with intensity 2 x 10 -3 W/m2 is perceived to be modestly loud. Your eardrum is 6 mm in diameter. How much energy will be transferred to your eardrum while listening to this sound for 1 minute?arrow_forwardA bat emits a sound whose frequency is 81.8 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 41.8 oC, so the speed of sound is not 343 m/s. Assume that air behaves like an ideal gas, and find the wavelength of the sound.arrow_forward
- Determine the velocity of sound in mercury, which has a bulk modulus of 2.8 × 10^10 and a density of 1.36 × 10^4 kg/m³.arrow_forwardUse the following information for determining sound intensity. The number of decibels β of a sound with an intensity of I watts per square meter is given by β = 10 log(I/I0), where I0 is an intensity of 10−12 watt per square meter, corresponding roughly to the faintest sound that can be heard by the human ear.Due to the installation of a muffler, the noise level of an engine was reduced from 87 to 69 decibels. Find the percent decrease in the intensity level of the noise as a result of the installation of the muffler. (Round your answer to the nearest whole number.)arrow_forwardFor Exercise, the formula L = 10 log (£) gives the loudness of sound L (in dB) based on the intensity of sound I (in W/m2). The value 10 = 10-12 W/m2 is the minimal threshold for hearing for midfrequency sounds. Hearing impairment is often measured according to the minimal sound level (in dB) detected by an individual for sounds at various frequencies. For one frequency, the table depicts the level of hearing impairment. Category Loudness (dB) Mild 26 sLs 40 Moderate 41 90 a. If the minimum intensity heard by an individual is 3.4 x 10-8 W/m2, determine if the individual has a hearing impairment. b. If the minimum loudness of sound detected by an individual is 30 dB, determine the corresponding intensity of sound.arrow_forward
