Features are disclosed for performing noise compensation so a level of noise may be audible in an output signal. For example, a first noise level of a first signal can be estimated. The first signal can be processed (e.g., by residual echo suppression) to determine a second signal, and a second noise level of the second signal can be estimated. Residual echo suppression can sometimes cause background noise to be eliminated, causing silence. If the second noise level is less than a product of the first noise level and a noise threshold, then a noise signal based on the first noise level can be determined, wherein the noise level of the noise signal is configured to be above a hearing threshold. The noise signal can be combined with the second signal to generate an output signal.
