Noise can be reduced through various methods, including sound insulation, sound barriers, and noise-canceling technologies. Acoustic treatments, such as foam panels and carpeting, absorb sound waves to minimize reflections. In transportation, design improvements and quieter machinery help lower noise levels. Additionally, regulations and urban planning can mitigate noise pollution in communities.
Being quieter.
thermal noise willbe reduce
ear plugs
Use Dynamat Extreme on the floor pan, it will reduce the road noise level.
Laws that require protection from loud noise in the workplace have achieved substantial reduction in noise induced hearing loss.

Window inserts can help reduce or block outside noise such as traffic, construction, or other environmental sounds.
The noise reduction ratio (NRR) measures how much background noise is reduced by a device or process, while the signal-to-noise ratio (SNR) compares the level of the desired signal to the level of background noise present in audio processing.
Reduce the emissions (the source sounds) shield the receptors (reducing immissions)
Well, a suppressor... suppresses. A flash suppressor reduced muzzle flash. A sound suppressor reduced noise emissions (although nothing like how they're portrayed in the movies).
Signal-to-Noise Ratio (SNR) measures the quality of the signal compared to the level of background noise, indicating how clear the audio is. Noise Reduction Rating (NRR) quantifies how much external noise is reduced by a device, such as headphones or earplugs, to improve the listening experience.
noise pollution can be reduced by following ways: prayer should be done in low voice means without mike.. ringing of bells should be avoided new ways should be taken instead of ringing bells. school should be made out of the city in silent places.
