Desired Silent Zone
The “Challenge”: Noise is Pollution
EU annual life years lost
due to noise pollution:• 61,000 life years lost to heart disease
• 45,000 life years for cognitive impairment
• 903,000 years for sleep disturbance
• 587,000 years for annoyance.
Health effects of noise• Sleep disturbance
• Cardiovascular effects
• Damage to work/school performance
• Hearing impairment including tinnitus

Noise Sources-Spectrum
Air flow spectrum example
Active Noise Control => effective in the low frequency band
Passive absorption => effective in the high frequency band
Broad band Noise => Requires a combination of
Passive and Active Noise Control
