A system configured to perform noise dependent volume control in order to increase a volume level of the playback audio in a noisy environment. For example, a device may adaptively increase gain based on an amount of ambient noise present in the environment. The device may determine a gain value based on a noise reference value and an estimated noise floor. The device may determine the estimated noise floor based on continuous noises, ignoring transient sounds and user speech. In addition, the device may include volume control logic to ensure that the volume level only increases when necessary and/or to control a rate at which the volume level increases. As part of selecting the volume level with which to generate the playback audio, the device may use a lookup table to convert between a device volume and a quantized volume used to perform noise dependent volume control.
