Mondo Knows Facts

The RIAA curve evened out record playback

A single equalisation standard was adopted in 1954 to end mismatched discs Cutting a disc with full bass would make the groove too wide and the stylus too likely to jump, so records are cut with bass reduced and treble boosted. Playback applies the mirror image. Labels had used several competing curves, and the RIAA curve, formalised in 1954, let any disc sound right on any turntable. It sits in Mondo's music collection, one of 200 facts that each trace back to the reference below.
