Medical schools will not look at your application until it is complete. This means your AMCAS has been verified, your secondary fee has been paid, your secondary has been sent in, your LORs have been received and you do not have an outstanding MCAT test date.
According to the Centers for Disease Control and Prevention, noise exceeding 90 decibels will feel loud to the ears. If movie theaters keep the volume at the proposed level, the amount of sound would be similar to the noise produced by heavy city traffic. In comparison, rock concerts today can peak at volumes of 110 decibels and greater.
We suspect the glass shown in the pictures and video on this page had invisible faults. How loud does the sound have to be? This depends on the glass. But for the glass we used the sound level was in the region of 135-140dB. (We didn't have the meter exactly where the glass was so we don't have an exact measure). To generate this needs very powerful loudspeakers - we used a hefty public address system.
