📚 What is Sound Intensity?
Sound waves carry energy. The intensity of sound is the amount of energy emitted by the sound wave per second per unit area. Louder sounds have more intensity!
🎧 Understanding Loudness
- Measurement: Loudness is measured in decibels (dB)
- Partial Hearing Loss: Cannot hear 45-60 dB
- Deafness: Cannot hear sounds up to 80 dB
- Warning: High-intensity sounds may damage hearing!
🧮 Sound Intensity Formula
I = P / A
I = Intensity (W/m²)
P = Power (Watts)
A = Area (m²)
