Testing speakers with a sweep.

The Tone generator: a 440 Hz sine wave in both ears at 20% volume

Let the sweep find the faults for you.

Setting it.

Choose where it starts and ends and how long it takes; 20 Hz to 20 kHz over ten seconds is a good first sweep.

By octaves.

By octaves gives each octave the same time, as we hear pitch; a straight line rushes the low notes.

Listening.

Listen for buzzes, sudden loud or quiet places, and where the sound fades away.
