Annoying continuing noise leads to an increase of adrenaline and production of cortisol. Good acoustics can therefore be extremely beneficial: more tranquillity and comfort. In a working environment, this leads to greater productivity, better concentration and less stress. In a restaurant it ensures intelligible conversations and less fatigue after an evening spent at the dinner table.
Good acoustics also have essential consequences at home: apart from a feeling of warmth and contentment, good acoustics also ensure better speech intelligibility, mainly during conversations that include multiple people, other sound sources such as the TV or hearing issues. Every situation has different acoustic requirements. EASY Noise Control tries to adjust the acoustic design completely to the space, the users and their activities. This is the way in which we are looking to achieve the objective of a productive, healthy and comfortable work space together.

Truth: Outdoor noise can be a significant problem. The location of a school can be a significant determinant of acoustical noise problems, especially if buildling users are expected to open windows.
Locations near major roads, airports, or any other source of noise can be a major problem, in some cases even with the windows closed. Measurement of ambient noise should be a part of site selection for a school. For a typical classroom, keep the head wall front reflective with hard surfaces.
Provide absorptive materials around the sides and back of the ceiling and the upper part of the wall, using a high NC material. Provide a relatively non-absorbent material in the middle of the ceiling and on the rest of the wall surfaces. Consider using carpet to reduce foot and furniture noise or use other methods. Also consider a sloping ceiling at the front of the classroom to reflect more sound out into the room. Absorption In acoustics, the energy of sound waves being taken in and trapped within a material rather than being bounced off or reflected.
Materials are rated in terms of their ability to absorb sounds. Articulation Class AC Rates the listener's ability to understand the spoken work within a space, expressed as a decimal with 1. The privacy index is derived from the A1 calculation. Lower A1 ratings less than 0. The sum of the weighted sound attenuations in a series of 15 test bands. NIC is based on hearing sensitivity rather than discernment of actual speech, which is the primary concern in open office layouts prevalent in acoustical design work.
Verify the rating methodolgy with manufacturer's published data. Ceiling Attenuation Class CAC Rates a ceiling's efficiency as a barrier to airborne sound transmission between adjacent closed offices. A single-figure rating derived from the normalized ceiling attenuation values in accordance with classification ASTM E , except that the resultant rating shall be designated ceiling attenuation class.
DBA A-weighted decibel A single-number measurement based on the decibel but weighted to approximate the response of the human ear with respect to frequencies. Decibel dB - A unit to express differences in power. In acoustics, equal to ten times the logarithm of the ratio of one sound and lower-intensity reference sound.
The dB level is a logarithm quantity; the maximum normal level is approximately dB. Fiberglass Panels - Glass strands laid in mats and formed into a rigid or semi-rigid board, sometimes requiring a separate stable material laminated to the fiberglass.
Mineral Wool - A man-made wool-like material of fine inorganic fibers made from slag, used as loose fill or formed into blanket, batt, clock, board, or slab shapes for thermal and acoustical insulation. Noise Reduction Coefficient NRC - Average sound absorption coefficient measured at four frequencies: , , 1, and 2, Hz which rates how well a ceiling or wall panel absorbs sound. NRC is the fraction of sound energy, averaged over all angles of direction and from low to high sound frequencies that is absorbed and not reflected.
Reverberation Time - Time required for a sound to decay to a value one millionth of its original intensity or to drop 60 decibels. Sound Transmission Class STC - A single-number rating of a wall or ceiling's efficiency as a barrier to airborne sound at 16 speech frequencies from to Hz. STC is a decibel measure of the difference between the sound energy striking the panel or construction on one side and the sound energy transmitted from the other side.

Your name and e-mail address: Select or. Introduction to Acoustics. Coefficients of absorption. In general, materials with more mass block sound more than lighter materials, especially for low frequencies which are very hard to block Sound likes to travel around barriers.
To be fully effective, walls should go from floor to the structure above, and holes should be carefully caulked or filled. Even small holes make a big difference. Most transmission failures are caused by cracks and holes. Batt insulation is useful, but it has to be installed very carefully or the effectiveness is compromised.
It's best to have it inspected by someone who understands this before walls are covered up. Unlike thermal insulation, even minor gaps, cracks, and other installation problems result in a major reduction in effectiveness. However, implementing acoustic treatment can do more than just improve the sound and quality of a location. Acoustic products can be beautiful, adding value to an environment in terms of sound and aesthetics.
We believe acoustic treatment should be an asset to a space, not just a functional piece. When acoustics are NOT an afterthought, you can create an environment that uses acoustics to its advantage, making it a point of interest. Absorbing unwanted sound and blocking out noise disturbance is the first step to improving architectural acoustics in a space. However, flipping the philosophy of acoustics on its head you can start to build design-led high-quality acoustic environments. In our following series of blogs on architectural acoustics, we will highlight how architects can implement acoustics into their project for the benefit of the sound of the space, as well as the design.
