Reduce the emissions (the source sounds) shield the receptors (reducing immissions)
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.
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.
