Abstract
An audio system capable of applying equal-loudness correction that takes into account a speaker sensitivity characterization includes a speaker, a microphone and a processor that is coupled to the microphone and the speaker. The processor is connected to a wireless communication network configured to receive an audio input, a group of user inputs, and a group of auxiliary inputs. The processor is configured to calculate the speaker sensitivity characterization apply the equal-loudness correction that takes into account the speaker sensitivity characterization. The audio system performs the speaker sensitivity characterization during an initial set-up cycle.

An audio system capable of applying equal-loudness correction that takes into account a speaker sensitivity characterization, comprising:
- a speaker;
- a microphone;
- and
- a processor coupled to the microphone and the speaker, the processor being connected to a wireless communication network configured to receive an audio input, a group of user inputs, and a group of auxiliary inputs, the processor being configured to:
- calculate said speaker sensitivity characterization;
- and
- apply said equal-loudness correction that takes into account said speaker sensitivity characterization, wherein the said audio system performs said speaker sensitivity characterization during an initial set-up cycle.
An audio system for applying equal-loudness correction that takes into account a speaker sensitivity characterization, comprising:
- a speaker, wherein the speaker contains a memory with embedded identifying information;
- and
- a processor coupled to the speaker, the processor being configured to:
- identify said speaker sensitivity characterization using the identifying information and a lookup table;
- and
- apply said equal-loudness correction that takes into account said speaker sensitivity characterization.
A method of sound playback applying equal-loudness correction that takes into account a speaker sensitivity characterization, comprising the steps of:
- providing an audio system comprising a speaker, a microphone, and a processor;
- sending a processor output signal from the processor to the speaker;
- producing a sound with the speaker based on the processor output signal;
- capturing the sound from the speaker with the microphone to be turned into a microphone output signal that that is sent to the processor;
- receiving and comparing the microphone output signal to the processor output signal using the processor;
- developing said speaker sensitivity characterization to be applied by the processor for said equal-loudness correction;
- and
- applying said equal-loudness correction to the processor output signal for the speaker to produce sound.
