We can Reduce Noise pollution by turning off appliances when not in use, use of earplugs, lowering the volume, planting more trees, regular maintenance of vehicles and machines etc. By controlling noise we can control negative health effects that noise pollution has on everyone. What is Noise?
How the money machine may help to reduce railway noise in Europe The need to reduce railway noise, particularly from freight transport in international traffic, is recognized by all stakeholders in the field. Solutions a... PD Vos - 《Journal of Sound & Vibration》 被引量: 28发表: 2003年 ...

Covering metal tables, metal wheels and other metal pieces with rubber to reduce noise vibration Modifying parts to reduce rattle and ringing Lining tumbling barrels, metal chutes and hoppers with an elastic material such as cork or hard rubber to reduce mechanical shock between parts ...
The detrimental effects of noise on physical and mental health can significantly reduce a worker's productivity. Struggling to communicate over loud noise can lead to misunderstandings and mistakes, and the fatigue from constant noise exposure can slow down the pace of work. ...
Sound andnoiseof all kinds can be very invasive and difficult to tune out no matter how hard you try. You don't have to suffer in the lack of silence, though. There are ways to reduce noise without causing a rift in the family or creating a neighborhood incident. ...
Alternatively, mounting pairs of identical components symmetrically on the top and bottom sides of the PCB can also help to reduce the noise level, because the two vibrations cancel each other out and the PCB stops resonating. The residual noise can be further reduced if the mechanical coupl...
Noise Vibration Harshness – how innovative sound design influences safetyJoanna Scheffel
But you also have to consider the time axis, because if changes in amplitude fall between samples, they cannot be measured. Systems with greater than 100 dB dynamic range and at least 200 kS/s sample rate can handle most applications. For shock, noise, and vibration applications, a ...
