Is Human Hearing Really That Bad?

Is 3dB really the smallest change in sound level that humans can actually hear? Is 10dB louder truly twice as loud? Why is our hearing so much worse than our other perceptions? Or, is the info about our hearing that is widely accepted as fact, completely wrong? let's do some tests and see. Bies and Hansen textbook Engineering Noise Control is generally credited with coming up with 33dB being the smallest difference people can hear and 10dB being twice as loud This is a great video for understanding decibels:    • Why decibels in acoustics - Acoustics Basics   And how to add and average decibels    • Adding & averaging decibel values   Here is a cool website with a bunch of interesting audio tests https://www.audiocheck.net/audiotests...
