Chosen Solution
I recently bought MacBook Air 13 inch (Model of December 2017). A friend called me to test the Handoff feature for calls, without muting the call. The stupid guy created an obvious feedback loop. Now at full volume, I hear a ringing sound. Have my speakers been damaged? I learned online that swipe-sine wave test can be helpful I’m on MacOS 10.13.4 Public Beta 7 (17E197a) So I installed AudioTest, ToneGenerator, SiGen I’m overwhelmed by the number of options I need to configure before playing any test sound Am I in the right direction? I just want to test the speakers for feedback loop damage Update (03/29/2018) At full volume, they don’t sound OK. Shouldn’t there be a standard way of finding out the health of the stereo?
I think you’re going to far here. If you damaged your speakers you would know when playing some music as well as vocal (talking & singing). Do these sound OK If they do then your OK. Feedback while hard on our ears in it self unless you let it run for a long, long time the risk is very little.
