ideasrule said:That's 4.00 micro-watts per meter squared, or 4.00 * 10^-6 W/m^2. It isn't 4 W/m^2..
To calculate dB with I, use the formula dB = 10log10(I/I0) where I is the intensity of the sound in watts per square meter and I0 is the reference intensity of 10-12 W/m2.
The reference intensity is the lowest level of sound that the human ear can detect, which is 10-12 W/m2.
Yes, dB is a unit of measurement for sound intensity and can be used to compare different types of sounds. However, it should be noted that dB measures the intensity of sound, not the pitch or quality.
No, there is no limit to the range of values for dB. It is a logarithmic scale, so the values can range from -∞ to ∞ depending on the intensity of the sound.
To convert dB to a linear scale, use the formula I = I0 10(dB/10) where I is the intensity in watts per square meter. This will give you the linear scale value of the sound intensity.
