In the band room, you tune your trumpet to Middle C, which has a fundamental frequency of 262 Hz. The temperature in the band room is 25º C. 1. What is the speed of this sound? 2. What is the wavelength of this sound? No matter what the temperature of the room is, this wavelength does not change. It is a property of the trumpet itself. 3. You go outside towards the football field, and the band director has you tune again. Suddenly everyone is playing the same Middle C with a frequency of 243 Hz. What is the temperature outside? 4. The player next to you blasts your ear with her trumpet and your ear hurts. Look up or estimate the area of your eardrum. 5. The pressure wave on your ear from this blast results in a difference of 60 Pascals between the inside and outside of your eardrum. What is the force on your eardrum as a result? Answer in Newtons. 6. What is the intensity of this trumpet blast in decibels?

You are listening to a speaker on a tripod in a room with a nice
smooth marble floor, as shown in the figure below. The speaker
emits sound of wavelength (lambda). The speaker s and your ear e

You are inside a room, 15 m from the west wall, which has two doors (similar to slits) and you are centered between the two open doors that are 3 m apart. Someone is blaring a 200 Hz tone outside the door so that it enters the doors as a plane wave. You hear a maximum intensity in your current position. a. As you walk (north) along the direction of the west wall with the doors (but maintain a distance...
