| Helmholtz Resonance | |
| Resonances
that occur when air or other fluids are excited and form standing waves
within a fixed volume. The traditional examples of Helmholtz resonance are
organ pipes and "blowing over the top of a bottle." As can be
imagined, Helmholtz resonance produces extremely detrimental frequency response
problems. When designing ports for vented enclosure, helmholtz resonance
must be considered in situations where port length is much greater than
port diameter. Helmholtz resonance can also be found in long, narrow enclosures
of any shape. Imaging: The sensation, provided by a well-designed, high-quality audio system, that the performers on the recording are actually performing in real space in front of the listeners. |
