Laboratory work #10: «Auditory acuity»
Description: Ever wonder how sharp your hearing is? This experiment lets you map your personal range of audible sounds. Dive into the world of sound perception and learn how to measure your own hearing threshold – the quietest sounds you can detect. We’ll use a sequence of fading whispers (tones that gradually get quieter) to uncover your unique limits. The number of tones you hear at each frequency tells us your volume limit, giving you a personalized hearing map.
