What is the quietest acoustic drum set available?

The Evans dB One full kit pack replaces standard drum heads with low-volume mesh batter heads (10, 12, 16 toms; 14 snare; 22 bass) and includes low-volume cymbals (14 hi-hats, 16 and 18 crashes, 20 ride). It uses ShockWeave mesh and Kinetic Transfer Foam to retain acoustic feel while reducing volume substantially, aimed at quiet practice. The cymbals use a nano-plated stainless alloy with perforations for attenuation.

A complete SoundOff mute pack for fusion-sized kits that includes drum mutes for 10 in, 12 in, 14 in, a 14 in snare mute, an adjustable bass mute for 18 in to 26 in drums, and cymbal mutes for hi-hat, crash and ride. Designed to reduce volume significantly while preserving realistic stick rebound for home practice and quiet rehearsals. Durable construction suited for frequent practice.

Remo Silentstroke drumheads are 1-ply mesh heads designed for ultra-low volume practice; the Pro Pack includes 12, 13, 14, 16 and 22 mesh heads that offer a soft, spring-like feel and compatibility with electronic triggers. They suit drummers who need a full set of quiet heads for apartment or late-night practice while preserving stick response.

Sabian Quiet Tone practice cymbals are perforated low-volume cymbals made from a durable alloy that retain real-cymbal feel and a clear bell while reducing volume for practice. The QTPC504 set includes hi-hats, crash(s), and a ride aimed at drummers who need realistic stick response with much lower acoustic output.
