Noise and Vibration Control Engineering
“I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.”
Ventilation Systems Units
Noise can be caused by anything. All sounds are components of noise, from vehicles navigating in traffic to chimney noise, from ventilation systems to air conditioning systems, from the noise coming from the neighboring house to the sound of technological devices. Noise is not just a sound made by a person, an animal, a vehicle or a machine. It is the sound integrity that emerges to a certain extent by the combination of all these sounds.
Urbanization and Noise
One of the problems that people face due to urbanization is undoubtedly noise. The machines that are included in our lives with the city life and the new mechanisms developed according to the working systems of these machines cause us to be exposed to many sounds that we were not familiar with before. Chimneys, ventilation systems, shutters, panels, which have an important place in urban life, have created a new type of noise called acoustic noise.
Causes of Noise in Chimney and Ventilation Systems
Mechanical noise in chimneys and ventilation systems is caused by the vibration and friction of the air moving towards the metal surface. This type of noise spreads to people's living spaces through chimney and ventilation systems together with the air. In order to eliminate this noise, sound insulation, which can be called acoustic sound insulation, should be made. According to the results of the technical examination to be made on the chimney, ventilation systems and acoustic noise source in the other region, acoustic blinds, silencers, etc. Appropriate work should be done quickly with intervention.
How to Prevent Vibration and Noise from Ventilation System and Out-lets
Various applications can be made to prevent noise in ventilation systems, chimneys and other ventilation systems. Anti-vibration elements are elements that prevent low-frequency noise caused by vibration in the system.
Acoustic silencers and louvres prevent the spread of noise, especially in ventilation systems, from air ducts to people's living spaces. Another component for sound suppression is sound absorbing fasteners. Acoustic fan cabinets, acoustic ducts and chimney insulation materials also help eliminate vibration and friction noise from outlets and ventilation systems.
