Abstract
Various improvements for mitigating low-frequency noise (LFN) in a wave making apparatuses are disclosed. These improvements use a variety of structures to mitigate LFN formation emanating from the rapid depressurization of the chambers during the release water into a pool. The improvements include a variable pressure relief/exhaust valve opening speeds, a pressure relief slit on the exhaust port, a secondary pressure relief/exhaust valve, an active absorption panel and a passive absorption panel. Each of these improvements may be used alone or in combination with each other.
