Abstract

A system for headphone equalization includes a stored set of predetermined tone burst reference signals and a stored set of predetermined tone burst test signals that form a range of frequencies used in a user specific audio test to develop a headphone correction filter. A predetermined tone burst reference signal and a predetermined tone burst test signal may intermittently and sequentially drive a transducer included in the headphone. A loudness of the predetermined tone burst reference signal may be fixed and a loudness of the predetermined tone burst test signal may be variable with a gain setting. The gain setting may be used to generate the headphone correction filter.

First claim

I claim:

1. A computing system comprising:
a processor;
a memory in communication with the processor, the memory comprising predetermined tone burst reference signals and predetermined tone burst test signals, the predetermined tone burst reference signals being at different audible frequencies from the predetermined tone burst test signals in each of a plurality of trial sets;
the processor configured to drive at least one headphone transducer sequentially and intermittently…
