Speaker Test checks every built-in speaker of your iPhone or iPad in under a minute. SPEAKER CHECK Play a tone on each speaker one by one, answer "heard it" or "didn't hear", and see the result: "2 of 2 speakers work". iPhone has two speakers, the bottom speaker and the earpiece at the top; a weak or silent one is easy to spot. STEREO LEFT / RIGHT Play a tone on the left, the right or both speakers and hear whether each side works on its own. WATER EJECT Pulses of a low 165 Hz tone make the speaker membrane vibrate, which can help push water and dust out of the grille after your phone gets wet.

Open Speaker check and answer after each tone. You see how many speakers work. Why does only one speaker play in the left / right test? On iPhone the left channel plays from the bottom speaker and the right channel from the earpiece at the top. Can it get water out of the speaker? The 165 Hz tone can help push water out.
