The decibel rating D| is related to the sound intensity I| by the formula D = 10 log_10 (I/10^-16)| for the noise level in decibels. Let D| and d| represent the decibel ratings of sounds of intensity I| and i|, respectively. Using properties of logarithms, find a simplified formula for the difference between the two ratings, D-d|, in terms of the two intensities I land i|. help (logarithms) (Enter log10 or logten for the base 10 logarithm.) If a sound's...

How are sound intensity, I and distance from the source, R related? Write hypotheses or claims about why each of these three relationships are linear or not linear: I vs. 1/R I vs. 1/R^2 I vs. R^2 Then, explain which one of these relationships is linear and why.

I kindly request, please show the steps, that is where I need help. I do not wish to waste my questions, so please show steps, that will really help me. Thank You. The decibel scale is logarithmic in intensity: β=10log10II0dB. In this formula, I0 is a reference intensity. To convert the intensity of sound waves from SI units to dB, I0 is taken to be 10−12W/m2. Once you know the intensity of a source in dB as measured at some...
