The measure of a sound’s pressure relative to the pressure around it; in its simplest form, quiet sounds produce waves with relatively small pressures. Loud noises produce sound waves with large pressures. A sound’s intensity will always diminish with distance, but the type of medium it passes through will affect how quickly it happens. In built environments, an ideal attenuation is usually achieved with a combination of sound blocking and sound absorption strategies
