Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second. The sensitivity (output SPL) rating of a speaker gives you a rough idea of how loud the speaker will play with a specific amount of power at a specific distance. Consider a speaker with this sensitivity rating: 85 dB / 1 watt / 1 meter. This speaker will produce sound at 85 dB, 1 meter away, when it is given an input power of 1 watt.

The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in . The frequency is the same as that of the source and is the number of waves that pass a point per unit time. That's why there are delay towers at big concerts and live music festivals. Because sound intensity greatly diminishes over longer distances, with a 6 dB loss of “volume” every time we double the distance of the sound source we need delay towers to keep the sound intensity going.

How far is it between Owen Sound and Niagara Falls. Owen Sound is located in Canada with (44.5672,-80.9435) coordinates and Niagara Falls is located in Canada with (43.1001,-79.0663) coordinates. The calculated flying distance from Owen Sound to Niagara Falls is equal to 138 miles which is equal to 222 km. According to the inverse square law, it can be shown that for each doubling of distance from a point source, the sound pressure level decreases by approximately 6 dB. The formula to calculate sound attenuation over distance for a point source is: Lp (R2) = Lp (R1) - 20·Log10(R2/R1) Lp (R1) = Sound Pressure Level at Initial Location.
