Abstract
In one aspect, opposing microphones may be mounted within a synthetic human ear. The synthetic human ear may form part of a head and torso simulator (HATS) system used for measuring output of any sound source, such as those embodied in headphones or loudspeakers. The opposing microphones may be used to calculate sound intensity and/or sound power, rather than just sound pressure level. The determined sound intensity/power can then be used to research and/or develop audio products, and/or quantify how a sound source is perceived regardless of acoustic loading on the HATS.
Claims20
An apparatus, comprising:
- a synthetic human ear, the synthetic human ear comprising a first microphone and comprising a second microphone;
- circuitry in the synthetic human ear, the circuitry configured for receiving input from the first and second microphones and providing the input to a processor system configured for determining, using the input from the first and second microphones, a sound power level, a sound intensity level, or both a sound power level and sound intensity level for adjusting at least one audio sound source.
A method, comprising:
- providing a synthetic human ear, the synthetic human ear comprising a first microphone and comprising a second microphone;
- providing circuitry in the synthetic human ear, the circuitry configured for receiving input from the first and second microphones and providing the input to a processor system, the processor system being configured to:
- generate, using at least the input from the circuitry, a value representing a fluid velocity;
- and
- use at least the fluid velocity to determine one or more of:
- sound intensity, sound power.
An apparatus, comprising:
- a synthetic human ear, the synthetic human ear comprising circuitry to derive one or more of:
- sound power, sound intensity.
