Here's the fun and interactive part of our website, at least for those with JavaScript capable browsers, and for those that think calculating decibels, reverb time, speech intelligibility and image size is fun. If you've ever wondered how many extra dB you're buying with those additional amplifiers and speakers; or wondered how loud a sound will be when you get further away from it; or need to build a 14dB attenuator for an unbalanced or balanced audio line; or want to know how sound levels add together; or just how long sound wavelengths are, then this might be just what you're after.
