Please show all necessary steps. 6. Suppose that the sound pressure level (SPL) coming from three different sources, co-located, is respectively 5dB, 3.3dB and 7.1dB What is the total sound pressure level received by an observer?
Please show all necessary steps. 7. If the acoustic intensity level increases by 6dB, by what factor does the sound (acoustic) intensity increase? What about a 9dB increase? What about a 12dB increase? NOTE: If we know the SPL (Li) or a sound at a distance di, we can work out the SPL (L2) at another distance, d2, from L2-L1 20 log1o
Please show all necessary steps and label parts i) and ii). 4. If a SPL of 80dB is measured at 10m, what is the level at (i) 15m? (ii) 7m?
Equation used to compute SPL (in dB) from sound pressure µbars. Equation: If a bulldozer emits a sound level of 90 dBA, what is the sound level (dBA) of two bulldozers next to each other?
Please show ALL steps when solving. 3. An input of 1 watt produces a SPL of 115dB at 1m from a loudspeaker. What is the SPL at 610cm from the loudspeaker?
please show all steps and calculations Determine the 1/1 Octave Band Sound Pressu Band Sound Pressure Levels (dB): Levels (dB) from the following 1/3 Octave Band Center Frequency (Hz) 63 100 Sound Pressure Level (dB) 87 97 87 89 80 76 160 200 250 74 400 75 74 79 80 630 800 1000 1250 1600 76 70 2500 4000 5000 57 53

5. The sound pressure levels (Lp) of seven different machines were 65, 72,79, 92, 83, 78 and 66 dB. Calculate the total sound pressure levels generated by these sources all operating simultaneously
please show all steps Suppose that a GPS satellite B is located 300 mi due east of GPS satellite A in the space. A car received the signal from B 1196.8 microseconds (us) before it received the signal from A. If the signal travels at the speed of 900ft/js, find Cartesian equation of the hyperbola on which the car lies. 300ml B VORT 1000D NOT HTAM EMAX AMOR
