A cyclist is using a loudspeaker to measure her speed. She cycles directly towards the loudspeaker which emits a sound with a constant frequency 261 Hz. The cyclist measures the frequency to be 269 Hz. You should assume that the speed of sound in air is 335 m s-¹. (a) Calculate the speed of the cyclist. (b) Describe briefly what the cyclist will hear as she passes the loudspeaker.

Based on the graph in Figure 17.36, what is the threshold of hearing in decibels for frequencies of 60, 400, 1000, 4000, and 15,000 Hz? Note that many AC electrical appliances produce 60 Hz, music is commonly 400 Hz, a reference frequency is 1000 Hz, your maximum sensitivity is near 4000 Hz, and many older TVs produce a 15,750 Hz whine. Figure 17.36 The relationship of loudness in phons to intensity level (in decibels) and intensity (in watts per meter squared) for persons with normal hearing. The curved lines are equal-loudness curves—all sounds on a given curve are perceived as equally loud. Phons and decibels are defined to be the same at 1000 Hz.
