How do we determine how far away sounds are

WebThe distance between one wave and the next gives the wavelength. For sounds all travelling at the same speed, high-frequency (high-pitched) sounds have waves very close together. Low-frequency sounds have a … WebWhat qualifies for “far enough away” depends on the size of the source- a simple rule of thumb is multiply the length of the widest part of the source by five. For instance, the output from an audio speaker 1” across is similar to a point source if …

Do low frequency sounds really carry longer distances?

Weban easy, useful rule: every time we move away from a sound source, doubling our distance from it, the sound pressure level decreases by 6 dB SPL. Vice versa if we move closer to the sound source, halving our distance from it, we perceive an increase in sound pressure of approximately 6 dB SPL. This rule is called the inverse distance law.
