Subwoofer Speaker Review A subwoofer is a type of speaker designed to emit low-frequency sound waves. Suppose a subwoofer is attached to a vertical pole. Of all the energy this subwoofer generates, 75 % of it is emitted forward in front of the suboofer, and 25 % is emitted backwards behind the subwoofer. Suppose a student takes a sound sensor and stands 1.0 m in front of the subwooferand 2.5 m below it. He measures a sound intensity level of...

Paisley stands in front of two speakers as shown which emit the same tone, in phase. She is 7.00 m from speaker A and 5.00 m fromB speaker B. a. What are the two lowest frequencies for which she hears: i. a loud sound? [171.5 Hz, 343 Hz] ii. a quiet sound [85.8 Hz, 257 Hz] d-5.00m A-7.00m b. The frequency of the speakers is then changed to 686 Hz Does Paisley hear a loud sound or a quiet sound?...

Question 5 Two speakers are placed 5m apart, are both forward facing, and emitting sound in phase, with a frequency of 1000 Hz. A person is standing in front of the speakers, a distance of 20 m from the mid point between the speakers. If the person walks parallel to the speakers (sidewards), how far do they need to walk before they hear a maximum, after walking through a minimum? What angle does this make relative to the perpendicular of...

You are standing a distance d
(2m) directly in front of one of two identical speakers, being
driven by the same signal generator, that are a distance h (5m)
apart. You walk in the positive direction starting at y=0 m, along
a line parallel to the line joining the two speakers. The speed of
sound is 340 m/s and the frequency is 170 HZ. As you walk, how many
times and where will you hear a maximum sound?
