Can you hear it?
I just played it in front of my two dc (10 and 8). Immediate affect from dd (10). Her hands shot to her ears to try and block it out and she begged me to turn it off. Ds could hear it but was more like what is that noise as opposed to actually bothered.
I can’t hear a thing (well I’m mostly deaf anyway) but it did leave me feeling a bit lightheaded.
