Abstract
Herein disclosed is a system that may be implemented within a headphone to facilitate hearing testing. Implementation of the system in the headphone may include implementation of tone generation circuitry and sound pressure level measurement circuitry being implemented in the headphone limiting the amount of calibration for accurate measurement when performing a hearing test.
Claims20
A system to be located within headphones for performing hearing testing, comprising:
- a tone generator to:
- receive an indication of a tone to be emitted from the headphones;
- and
- cause the tone to be emitted by a speaker within the headphones;
- and
- a sound pressure level (SPL) measurement element to:
- receive an indication of the tone detected by a microphone within the headphones;
- and
- determine an SPL of the tone detected by the microphone, wherein the SPL is to be used to verify that the SPL is equal to an intended SPL for the tone.
6 more elements
Headphones, comprising:
- a speaker to emit tones;
- a tone generator coupled to the speaker to cause the speaker to emit a first tone;
- a microphone to detect the first tone emitted by the speaker;
- and
- a sound pressure level (SPL) measurement element coupled to the microphone to determine an SPL of the first tone emitted by the speaker based on detection of the first tone by the microphone, wherein the determined SPL is to be utilized to determine whether to adjust SPLs of the tones to be emitted by the speaker.
2 more elements
A method of performing a hearing test by headphones, comprising:
- causing, by a tone generator located within the headphones, a tone to be emitted by a speaker of the headphones;
- detecting, by a microphone located within the headphones, the tone emitted by the speaker;
- determining, by a sound pressure level (SPL) located within the headphones, an SPL of the tone emitted by the speaker;
- comparing the determined SPL of the tone with an intended SPL for the tone;
- and
- determining whether to adjust SPLs of subsequent tones to be emitted by the speaker based on the comparison of the determined SPL of the tone with the intended SPL of the tone.
