Episode notes
Noise Is Contextual And Human-Made
- Noise is defined as unwanted sound and often stems from human sources like machines and vehicles.
- What counts as noise varies by person and context, making regulation complex.
Decibels Are Logarithmic Intensities
- Decibels use a logarithmic scale so small increases mean large intensity jumps.
- A 10 dB rise is ten times more intense, making loudness growth non-linear.

- 'Hidden hearing loss' can occur when neural connections are damaged while standard tests look normal.
- Lower-intensity noise can cause lasting auditory pathway damage beyond obvious hearing loss.
