Zonal Noise Polluters

Point Noise Polluters

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
