Thousands of marine species from microscopic zooplankton to the largest cetaceans rely on sound for survival and many have evolved unique oral and aural adaptations. Understanding them better could ...

So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency ...

Turbulence can also occur in sound waves that propagate chaotically in certain media, such as superfluid helium. In the 1970s, Soviet scientists proposed that turbulence occurs when sound waves ...

Discover Clear Wave, the free iPhone app designed to expel water from your speakers using low-frequency sound https://watereject.top Most iPhone users will be scared to even think about dropping their ...

the sine wave remained smooth. Running under these heavier loads, we measured the highest sound levels for the EU2200i at 81.2 decibels at the generator. Aside from the clean enclosure ...

For a larger generator, the GP6500 isn’t excessively loud; we logged sound levels at 83.3 decibels under load from 25 feet away. When we hooked up an oscilloscope and monitored the sine wave of ...
