Something I feel should be researched more is whether it is possible to property disable the high-pitched ringing sound that plays whenever an explosion goes off very close to the player. While done for the sake of realism, it is ear-grating, especially for those of us with sensitive hearing and/or hearing disabilities. The sound effect is generated in-engine, so it's not possible to mod it out simply by replacing an audio file. Setting the cheat cvar dsp_off to 1 disables it, but it also disables a lot of other important audio processing filters. Valve, pls fix.
