Abstract
The present invention provides a relatively compact-sized pulse combustor which efficiently reduces an undesirable explosion and combustion noise without any bulky muffler. In the pulse combustor of the invention, a compensating sound is generated in an exhaust conduit synchronously with pulsative explosion and combustion. The compensating sound has a sound pressure identical with that of a noise in the exhaust conduit but a phase opposite to that of the noise, thus effectively compensating the noise in the exhaust conduit and efficiently reducing the noise from an exhaust outlet.
