SOUND-PRODUCING DEVICES; METHODS OR DEVICES FOR PROTECTING AGAINST, OR FOR DAMPING, NOISE OR OTHER ACOUSTIC WAVES IN GENERAL; ACOUSTICS NOT OTHERWISE PROVIDED FOR

Introduced: September 1968

Description

G10K encompasses mechanical and electromechanical devices that generate, transmit, or manipulate sound waves, as well as technologies for noise control and acoustic damping across general applications. This includes loudspeakers, sirens, horns, acoustic transducers, and sound reproduction systems, alongside noise reduction methods such as sound-absorbing materials, silencers, vibration isolation, and active noise cancellation. The classification also covers general acoustic phenomena and measurement techniques not covered by more specialized acoustics classes dedicated to specific musical instruments or underwater acoustics. Adjacent specialized classes (G10B-G10H for musical instruments, G10L for speech analysis) are excluded from this scope.

Of 10 combined children, 8 exist in both systems.

2 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

3 shared codes have differing titles between IPC and CPC.
