Loudness-based compensation systems and techniques are described which provide audio compensation in noisy environments. Loudness approximations are determined for an audio block both by itself and in the presence of background noise. These approximations utilize compression of audio intensity within frequency bands in order to better reflect listeners' hearing perception. From these loudness approximations, a gain is determined for the audio block and then applied in such a manner that the effect is not jarring to listeners.
