One of the challenges of room acoustics , regarding simulation and installation, is precisely remodeling a room over the whole frequency range. This post discusses a blended approach for installing the acoustics of the room where the results from multiple techniques are incorporated into a single model, thereby enhancing precision and maintaining viability. Let us learn how this can be done. Room acoustics review Here we will discuss how the first two techniques can be blended to get a broadband impulse response for a room. Response of room impulse Imagine that an air-filled balloon is popped in a room while microphone at some other location in the room records the pressure of the acoustic solutions as a function of time. The microphone will get direct sound from the first wavefront and also a superposition of all reflected signals from the waves travelling and bouncing off the ceiling, floor, walls and other objects in the room.  Remodeling the room While installing the floating ...

Inplant acoustic enclosures enclose noisy equipment in a chamber or room. For optimal acoustic performance, the exterior of the enclosure should be made with thick and robust material like galvanized steel while the interiors should be covered with absorbent material like acoustic wool. To prevent noise from escaping through the ventilation system, the air outlets and inlets should be fitted with silencers. An enclosure also comes with acoustic windows and doors, acoustic tunnels at the exit and entrance of the conveyors and utmost reduction of openings.  What kind of noise control solutions you are looking for? To calculate the desired soundproofing, the sound created by the machinery can be measured by using a sound level meter. Ideally, the noise control solutions should lessen noise levels below 85 dB, which is the legal limit in most of the Canadian provinces.  What are the dimensions of mechanical room noise? The exterior and interior dimensions of the mechanical room ...

Sound control doors are doors that have been heavily insulated to prevent vibration and sound from passing through the door. The robust acoustic seals and thick insulation of the door assist to accomplish this in situations where noise reduction is desired. In respect to the popular notion, just filing up a hollow core door doesn’t make it a soundproof door.  Why do I require sound control doors? There are several reasons that people might want a soundproof acoustic door and noise control products . The most apparent reason is for venues that are noisy and loud, like recording studio, night clubs or other concert or show venues. The military ambiences and doctor’s offices need privacy and often you will notice soundproof doors used to assist in safeguarding the confidentiality of discussion in these rooms. How can you soundproof an existing door? Doors made of dense, robust, and solid wood or steel are not soundproof unless they have acoustic seals. The main feature of sound absor...

Noise pollution is everywhere. According to research, more than 4 million people suffer from damaging levels of noise regularly while working in the USA.  Loud noises not only impact hearing, but they can cause stress, enhance health issues, and create a feeling of irritation in animals and people.  Extremely loud noise interferes with the way animals function and whether they can survive. This led to the growing demand of noise barrier walls . Issues with wild life and noises Many people don’t understand the extent that noise can impact animals. In some scenarios, animals are seriously impacted by the noises of farm machines, factories, residential complexes, construction and traffic sounds. Regular event venues such as sports centers, stadiums and concert halls impact the animals that live near them and you may have to look for sound control curtains to protect them.    Sonar is something that hampers the life of the ocean wildlife as the sound interferes in commu...
