The engine exhales through a 21-liter muffler and twin 15-liter resonators, and uses a cast-aluminum oil pan and liquid-filled engine mounts to reduce NVH levels. |
Use Helmholtz resonators, diaphragmatic absorbers, or plenum absorbers for large rooms having reflective surfaces and in need of speech intelligibility. |
The DFB substrate provides the low threshold operation and wavelength selectable capabilities inherent to resonators based on this approach. |
A combination of Helmholtz resonators on the back wall and absorbers in the ceiling help control the low frequencies. |
One of the commonest African names for the xylophone, usually with calabash resonators. |
The frequency of nanomechanical resonators is generally determined by reflecting a laser off the resonator. |
