Sound level meter |
摘要 |
A sound lever meter is described which combines in one meter the multiplicity of measuring devices for measuring sound sources or sound filters that are near or far from the head, and which can be used for arbitrary instances of acoustic irradiation by switching over an electric equalising network. It also facilitates the mono or stereo recording of sound signals of arbitrary sound fields.
