The equivalent acoustic noise level produced by a microphone and its internal electronics when no intended sound is present.
The equivalent acoustic noise level produced by a microphone and its internal electronics when no intended sound is present.
Use cases
- Self-noise is especially relevant when recording quiet dialogue, Foley, ambience, or distant sources with substantial gain. Compare manufacturer measurements made with the same weighting and method; the microphone is only one contributor to the complete recorder, preamplifier, wireless, and environment noise floor.
Setup
- Confirm the intended use, inspect the equipment, and coordinate placement with the responsible department.
Safety notes
- Use only within manufacturer ratings and the production safety plan.
