WAVES and SOUND Worksheet 1. When an automobile moves towards a listener, the sound of its horn seems relatively a. low pitched b. high pitched c. normal 2. When the automobile moves away from the listener, its horn seems a. low pitched b. high pitched c. normal 3. The changed pitch of the Doppler effect is due to changes in

It occurs when the distance between the source of a sound and the observer is changing. As the source approaches an observer, the observer hears the pitch (or

Preview and Download !The chorus effect simulates the acoustic transformation. A well-known method for simulating the chorus effect, which is popularly used for electric guitars or synthesizers, is based on time-varying delay-lines. The method achieves the effect by detuning copies of the original signal and summing the detuned copies back with the original. The
