What's the link between the frequency of sound wave and the intensity of sound wave? A serious byproduct of this exposure is sensory-neural hearing loss, which cannot be restored to normal. Decibel X displays real-time sound levels both numerically (in decibels) as well as visually in beautiful wave and bar graphs. Dividing 100 by 10 gives us the ratio between them, which is 10. This is why I love this trick. If the base line, lg(10^-12/10^-12) dB or 0dB, corresponds to a frequency of 2997Hz, how a human ear is possible to percept sound wave weaker than that 2997Hz?
