Siddhartha saved up money from his summer job to buy a powerful home theater system. When shopping for the best buy in a home theater system the sales representative informs Siddhartha that the more expensive models are worth the money because they a. amplify sound up to 160 dB. b. buffer sounds that reach 60 dB. c. filter out frequencies below 10000 Hz. d. boost frequencies below 80 Hz.

Boost frequency below 80Hz

Explanation:

Speakers can produce 20Hz(deep bass) to 20Khz(piercingly high frequency) ranges of frequency.

Typically, a home theater ranges from 20 to 200Hz, and it is expected to operate the home theater less than an 100Hz. THX (Tomlinson Holman's eXperiment) approved system should operate below 80Hz. Low frequency sound appear to be relief the mind. It is called bass.

The recommended frequency is between 80Hz to 120Hz based on the settings, some ratings include ±3 dB deviation. This shows how far the sound deviates from a neutral or "flat" response; the lower the number the better. So it is wise for the sales representative to inform her to buy a home speaker the boost frequency below 80Hz
