A small speaker delivers 2.0 W of audio output. How close can the person get to the speaker without hurting his ears? 1:44:04 Question 31 to 40: Sounds Waves - Exercise : Chapter 16 Que. 31 Two speakers S, and S, driven by the same amplifier, are placed at y = 1.0 m and y= -1.0 m. The speakers vibrate in phase at 600 Hz. A man stands at a point on the X-axis at a very large distance from the origin and starts moving parallel to the Y-axis. The speed of sound in air is 330 ms. (a) At what angle will the intensity of sound drop to a minimum for the first time? (b) At what angle will he hear a maximum of sound intensity for the first time? (c) If he continues to walk along the line, how many more maxima can he hear? 3:04:12 Website Overview ======================================================= Why study from Magnet Brains?
