Question 5.
A nailing gun produces a short, loud sound as the tool drives in a nail. The sound has an intensity
level of 136 dB at the ear of the user (0.2 m from the tool), for a duration of 0.1 s.
(a) What is the corresponding sound intensity? (1.5 marks)
(b) The tool is a good approximation to a point source of sound. What is the rate at which it
produces sound energy? (1.5 marks)
(c) How much energy would be transported to the user’s eardrum (of area 6.0 x 10-5 m2) as the
tool drives in a nail? (1.5 marks)
(d) Explain why earplugs or earmuffs are recommended to be worn when using the tool.
(0.5 mark)

A loud factory machine produces sound having a displacement amplitude in air of 1.00 μm,

A loud factory machine produces sound having a displacement amplitude in air of 1.00 μm, but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 Pa. Under the conditions of this factory, the bulk modulus of air is 1.23×105 Pa . The speed of sound in air is 344 m/s.Part AWhat is the highest-frequency sound to which this machine can...

There are two main ways to describe how loud a sound is. One is that you can describe its intensity, I, measured in W/m2, which is the amount of energy per unit time, per unit area, transported by the sound. However, this is not very close to the human experience of sound loudness. The human experience of loudness (actually like the way most of our senses work) is that each factor of 10 in intensity sounds like the same sized...

A woman stands a distance d from a loud motor that emits sound uniformly in all directions. The sound intensity at her position is an uncomfortable 3.3×10-3 W/m2. At a distance 2.9 times as far from the motor, what are (a) the sound intensity and (b) the sound intensity level relative to the threshold of hearing?
