Noise-induced hearing loss can unmask audible difference tones

Evidence

A hearing threshold shift, especially when of sensorineural origin, is often frequency dependent. Consequently, hearing can be, for instance, fully functional in one frequency range, have linear attenuation in another frequency range, and recruitment in a third frequency range. This poses certain challenges in the design and individual fitting of hearing instruments, as discussed later in Section 19.5. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2660 (#qualifies, via linked claim)
