Noise Makes You Sick – How Can We Deal With Noise Pollution?
This documentary examines the health implications of noise pollution and explores various innovative solutions designed to mitigate its effects. It presents case studies and technological advancements aimed at reducing noise in different environments.
The program investigates methods such as architectural interventions, including the use of “crossbars” in urban settings to block street noise. It also covers advancements in transportation, such as “whisper brakes” for trains, and emerging technologies like “antisound” systems for industrial machinery. Additionally, the documentary features research into biomimicry, specifically the study of owl flight for quieter aircraft design.

Frequently Asked Questions
What are “crossbars” in the context of noise reduction?
“Crossbars” refer to new building structures that are strategically placed to fill gaps between existing rows of houses, thereby creating a barrier that reduces street noise for residents.
How do “whisper brakes” contribute to noise reduction?
“Whisper brakes” are a type of braking system installed on rail cars designed to reduce the noise generated by trains, particularly in densely populated areas.
What is the principle behind “antisound” technology?
“Antisound” technology works by generating sound waves that are precisely out of phase with existing noise, effectively canceling out or significantly reducing the original sound, particularly low frequencies.
How is owl flight relevant to quieter aircraft?
The silent flight of owls serves as a model for researchers in aerodynamics and acoustics, who study their wing structures and flight mechanics to develop quieter aircraft designs.
