(III) Expensive amplifier A is rated at 220 W, while the moremodest amplifier B is rated at 45 W. (a) Estimate the soundlevel in decibels you would expect at a point 3.5 m from aloudspeaker connected in turn to each amp. (b) Will theexpensive amp sound twice as loud as the cheaper one?
(II) You are trying to decide between two new stereoamplifiers. One is rated at 75 W per channel and the otheris rated at 120 W per channel. In terms of dB, how muchlouder will the more powerful amplifier be when both areproducing sound at their maximum levels?
In audio and communications systems, the gain, ?, in decibels is definedfor an amplifier as? = 10 ????!"#?!"where Pin is the power input to the system and Pout is the power output.(a) A particular amplifier puts out 135 W of power for an input of 1.0 mW.What is its gain in dB? (b) If a signal-to-noise ratio of 93 dB is specified,what is the noise power if the output signal is 10 W?
