Abstract
A listening sound obtaining method for a voice amplification system, including a sound collector, an amplifier, and a sound emitter, that sends a speech sound of a speaker to a listener through at least a voice amplification transfer route that includes the sound collector, the amplifier, and the sound emitter, the listening sound obtaining method obtains a first sound pressure at any position on the voice amplification transfer route of the speech sound, and calculates a second sound pressure at a listening position of the listener based on the obtained first sound pressure.

A listening sound obtaining method for a voice amplification system, including a sound collector, an amplifier, and a sound emitter, that sends a speech sound of a speaker to a listener through at least a voice amplification transfer route that includes the sound collector, the amplifier, and the sound emitter, the listening sound obtaining method comprising:
- obtaining a first sound pressure at any position on the voice amplification transfer route of the speech sound;
- and
- calculating a second sound pressure at a listening position of the listener based on the obtained first sound pressure.
A listening sound obtaining apparatus that obtains, in a voice amplification system, including a sound collector, an amplifier, and a sound emitter, that sends an speech sound of an speaker to a listener through at least a voice amplification transfer route that includes the sound collector, the amplifier, and the sound emitter, a sound pressure at a listening position of the listener, the listening sound obtaining apparatus comprising:
- a controller that:
- obtains a first sound pressure at any position on the voice amplification transfer route of the speech sound;
- and
- calculates a second sound pressure at a listening position of the listener based on the obtained first sound pressure.
