We present a perceptually motivated, real-time hearing loss simulation for use in audio production. The implementation builds on a previous simulation, but is now real-time, low latency, and available as a stereo audio effect plug-in with more accurate modelling of hearing loss. It offers the option of isolating and customizing high frequency threshold attenuations on each ear, corresponding to the audiogram information. The simulation also provides the option of incorporating additional suprathreshold effects such as spectral smearing, rapid loudness growth and loss of temporal resolution on audio. The underlying psychoacoustic principles are described, and results are presented to show the simulation’s performance.
