Speaker test tones: check selected frequencies by ear
Use up to four fixed sine tones at a time to check selected speaker frequencies by ear. Change the tones manually to compare points across the range. Use measurement software and a microphone for a response curve.
This tool plays up to four fixed sine tones at once. Adjust the frequencies manually and listen for changes, rattles, or room peaks at selected points. It is a listening check, not a continuous sweep or calibrated frequency-response measurement.

How this is calculated
The generator can play up to four fixed frequencies at a time, so an eight-point check must be done in multiple steps. Try selected points such as 100, 250, 500, 1000, 2000, 4000, 8000, and 16000 Hz individually or in small groups, then compare the left and right speakers. A continuous sweep or calibrated microphone is needed to measure a speaker's full frequency response.
Verdict
Treat these fixed sine tones as a basic listening check. They can help you notice a rattle or a difference between selected frequencies, but they do not produce a continuous sweep or measure the speaker's full response.
