Suppose that a sinusoidal interference has been added to desirable music that has frequency components ranging from 15-Hz to 20 KHz. The frequency of the interference slowly varies in the range of 0.950 kHz to 0.990 kHz. A filter that attenuates the interference by at least 20dB and passes most of the audio components is desired. Hint: Draw a sketch of the x-axis showing all the frequency components on the x-axis

A 1,720-Hz tone is played on a stereo in an open field. A person stands at a point that is 4 m from one of the speakers and 4.4 m from the other. What must the minimum wavelength be for the person to hear the tone? (Hint: because of interference, two waves add constructively or destructively. If the sound is heard the interference must be constructive. For interference to be constructive, the difference in distance must be a multiple of the wavelength. That is, the difference in distances from the speakers must be 1 wavelength, two wavelengths, three wavelengths, etc.)

An interference pattern is setup with two point sources of the same frequency vibrating in phase. A point on the second nodal line is 25.0 cm from one source, 29.5 cm from the other source. The speed of the waves is 7.5 cm/sec. Calculate the wavelength and the frequency of the sources.
What is the resultant sound level when an 81-dB sound and an 87-dB sound are heard simultaneously? This question is in the library, but, some of the answers is not visible.

The speaker depicted below (See slide 10 of chapter 16 for a detailed explanation) emits a sound of frequency 779 Hz. Due to the path difference (r2 - r1) the receiver detects a constructive interference. Find the distance by which r2 needs to be adjusted to detect the very next destructive interference. (Take speed of sound as 343 m/s).
Speaker 1 is at x = 0 and speaker 2 is to the right and facing it at x = 3 m. The speakers are to the same amplifier, which plays a tone of unknown frequency. If the first point of destructive interference is 0.18 m to the left of the center, find the frequency in Hz. The speed of sound is 345 m/s. connected continuous f = Hz
