Please show all necessary steps. 5. Suppose that the sound pressure level (SPL) coming from three different sources, co-located, is 3.3dB. 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?
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 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
Please show all the necessary steps to get the answers eo Figure 1.1 Show that the transfer function relating the input voltage e, and output voltage eo for the circuit shown in figure 1.1 is given by E(6) LCs +RCS +1 a. b. The values ofL, R and C are 2H, 122 and 0.1F respectively. Determine eo(t) when a 5V step input is applied. Using the initial and final value theorem, find the initial and final value of the output...
Can you please explain with all steps and necessary equations? Thank you! 6. The force constant of the CO group in a peptide link is approximately 1.2 kN m'. At what wavenumber would you expect it to absorb? Treat the CO subunit as a separate molecule to find the reduced mass.
Please I am in exam. Please answer these questios fast... Q5 Calculate the total sound pressure level caused by a combination of sounds with the following SPLs 20dB+20dB+20dB. Q6.If the sound 5 meters from the stage at a rock concert is at the 100dB what is the intensity level 10 meters away. Q7. The intensity of sound from a loud speaker, measured at a distance of 3 meters from the source is 3.0x10--3 W/m2 (a) Calculate the intensity of the...
