Some Fundamentals of Acoustic Design
When it comes to acoustic design, it can be difficult to comprehend. For starters acoustics are a challenge for both architects and designers. Acoustics involves all aspects of design and many factors need to be taken into account to avoid a multitude of issues. Architects must take into consideration factors such as room size, room finishes, wall and floor construction and mechanical/electrical services to name just a few. These can all affect the acoustics within a room. To avoid acoustics from becoming an issue, acoustical design services can assist and are best engaged early in the design process.
Breaking it Down
No space is the same and architects strive to design buildings which are unique, attractive and functional. With that said, acoustical solutions within a building are not the same as the next. Many different things can go wrong when it comes to acoustics. For example, if HVAC noise is not addressed during design, a newly constructed building could have excessive sound levels that do not allow for the space to be used for its intended purpose. Often, attempting to resolve these issues after a building has been constructed is disruptive, difficult and cost prohibitive.
In a restaurant, sound absorption can be beneficial to create a more intimate setting as noise is reduced. In highly reflective spaces without sound absorption, people have great difficulty hearing and understanding conversation with others at their table. Gymnasiums are another example of a space where sound absorption is often ignored. In a school setting, reverberant spaces and poor speech intelligibility can be fatiguing to the occupants and pose a safety issue if students do not clearly understand instructions from their teacher.. These are just a few examples of how acoustic engineering services can provide efficient solutions to common sound issues. For more visit source.

Controlling Industrial Noise Emission
Addressing noise emission is a key component to ensure comfort and respect of surrounding areas. When it comes to industrial noise emissions, limiting operations to appropriate sound levels is a requirement that assists with avoiding unwanted disturbances to your neighbours. Bringing in acoustical consultants to review and reduce noise emissions allows for many benefits for both the operator and the surrounding community.
Disturbance of Noise Emissions
Every area provides different limits for environmental noise emissions. Noise requirements are typically limited to avoid complaints or community disturbances. Constant elevated noise emissions not only disturb surrounding areas, but can negatively affect the workers as well. Workers exposed to elevated noise emissions are at risk for health issues such as hearing loss. Further, the continuous onset of elevated noises can result in a loss of the ability to use your property (or the surrounding properties) as intended. Abiding by the environmental noise emission limits can result in a better environment for all and is a regulatory requirement.
Sound Limits
The sound level limits will typically depend on the area in question. In areas where the ambient sound levels are high, such as in the city with ongoing traffic, the sound level limits will likely be higher. However, in a rural area, where the ambient sound levels are low, sound level limits tend to be more stringent. When sound level limits are exceeded, there is an increased risk of noise complaints. Before the situation gets out of hand, finding ways to reduce the sound levels of your equipment and activities is beneficial to all. Contacting an acoustical design consultant to assist in reducing your sound emissions is beneficial for your business and the surrounding areas. For more visit

The Steps of an Acoustic Audit
When going through the process of noise impact assessments, there are a few key focuses. The main aspect is ensuring the noise levels in the facility are compliant with regulations and guidelines. To ensure your facility is ready for an audit, consider working with a noise assessment consultant to ensure success. The audit process consists of steps including:
ECA and Acoustic Assessment Report
In Ontario, all industrial operations need to obtain approval from the Ministry of Environment, Conservations and Parks (MECP). Subject to your NAICS code, you either need to obtain an Environmental Compliance Approval (ECA) or register in the Environmental Activity and Sector Registry (EASR). As part of the application an Acoustic Assessment Report (AAR of noise report) is included to support the submission. If noise mitigation is required, a Noise Abatement Action Plan (NAAP) is included. The NAAP will outline the noise mitigation measures and any operational restrictions that are required.

How Vibrations Affect Structures and People
Defining Vibrations
Vibrations are motions that can affect structures and people. There are different types of vibrations. Periodic vibrations are defined as oscillatory motion with a repetitive motion. Random vibrations are instantaneous and occur at different times that are not predictable. Vibrations can occur anywhere from a multitude of sources. Construction is a common example of activities that can result in vibration frequencies. The use of generators, jackhammers, and drills can cause waves of vibrations. Transportation services, specifically train activity, can induce higher vibration levels. High vibration levels can impact structures and potentially cause damage. To avoid hazards and damage from occurring, vibration monitoring can be an effective way to ensure the safety of people and structures.
How Vibrations Can Affect Structures
In 1940, the Tacoma Narrows bridge in Washington collapsed as a result of vibration. The suspension bridge was designed without thought of how wind can cause high torsional oscillations. The wind reached up to 40 mph when it collapsed. The vibrations that caused the collapse have been heavily studied. When structures are being built, many contractors are now required to have a third party complete construction vibration monitoring to reduce the risk of potential structural damage from their activities to the neighbouring properties. Long term unattended vibration monitoring can also bring awareness of imbalances and misalignments. If vibration monitoring was around during the Tacoma Narrow suspension bridge construction, a warning of impending failure might have been predicted. For more visit source.

Building Services Noise Mitigation in the Design Process
A building’s basic utilities include electrical service, lighting, plumbing, heating/cooling and air handling systems. Of these utilities, air handling and plumbing are the two that present more wide ranging for possible noise and vibration problems, with the air handling distribution system being the more dominant. Acoustical consultants can contribute noise and vibration solutions in the design process, significantly reducing future problems.
Noise From Pipes
Plumbing systems can produce and transmit noise throughout a building. A metal pipe, as well as the fluid within the pipe, are good conductors of sound, and there was a time when tenants of old buildings would communicate with the building superintendent by banging on their radiator. This was a signal that they wanted more heat, and the banging could be heard ten floors below, in the boiler room. The musical group The Pointer Sisters immortalized this method in their song, “Banging On The Pipes.” Sometimes a building’s plumbing produces noise of its own, and this is almost always due to pipes that are not securely mounted or acoustically isolated at the point of attachment to the building walls or floors. A residential acoustic consultant can help design a plumbing system that is quiet and free of vibration and will stay that way for decades to come. Visit source for more info.

Combining ‘Open Concept’ Architecture and Acoustic Design
Open-concept architecture seeks to create airy, soaring spaces. Fewer walls and barriers can eliminate a claustrophobic, stuffy, or isolated feeling. Open designs make a space feel bigger and lighter, and who wouldn’t want that? It sounds great.
Except it doesn’t sound great. Such spaces are frequently designed without any input from acoustical consultants, often with troubling results. Let’s examine the main design factors that go into open-concept architecture.
Room Volume
As any acoustic consultant in Toronto can tell you, the amount of reverberation within a space is the factor that most defines a room’s acoustical character. Reverberation is the buildup of sound energy due to the bouncing around of sound waves as they strike various hard surfaces. If a sound wave strikes a hard, reflective surface, it is largely reflected back out into the room as reverberation. If it strikes a soft, absorbent surface, it is mostly absorbed.

The Importance of Auralization in Acoustic Engineering
30 Wertheim Court, Unit 25, Richmond Hill, Ontario, L4B 1B9. Canada
Your architectural team has presented a breathtaking rendering of a proposed hotel lobby. It features expansive glass and marble vistas, with windows stretching from lobby floor to third-floor ceiling. It is certain to become one of the most memorable hotel lobby experiences that anyone will ever have. But there is a great unanswered question, which is, will it be memorable for the wrong reason? Large acoustic spaces, designed with appearance in mind, and without the benefit of acoustical design services, often result in a space that is beautiful to look at, but also disappointing or even unusable acoustically.
Auralization is the process of creating an acoustic simulation of what a space will sound like, in advance of its actual creation. It is an audio corollary to the term “visualization.” With the use of extensive computer modeling and acoustic rendering, a future room can be auditioned with a variety of different acoustical engineering service options. It removes guesswork and replaces the act of hoping everything will turn out sounding okay, with the certainty that everything absolutely will sound excellent.
