absorption. The ceiling is completely revealed to the human eye, and with its services (the fans, ductwork and lighting) on view they can directly contribute to the background noise levels resulting in a poor acoustic performance of the space.
What ar What are the options?
Many elements come into play when managing a space’s acoustics, including the way air conditioning systems are designed. To create a peaceful, workable and visually-engaging environment, the right air distribution system must be selected. Some environments often require tailor-made, bespoke solutions to minimise noisy acoustics; there are, for example, these kinds of air distribution systems in acoustically-sensitive buildings such as the Elbphilharmonie Hamburg, Germany. A concert hall on this scale demanded acoustically-advanced solutions; bespoke sound control was completely necessary in this location as noise could interfere with the artist’s focus and the paying audience’s enjoyment.
But in terms of air distribution systems for commercial spaces, products such as the Krantz AVA Cs system (Air Ventilation And Cooling system) keep acoustic interference to a minimum and can actively improve the space. These systems are designed to great detail and sophistication; they do not contain any moving mechanical parts so the systems cannot generate any noise. Through convective radiant panels, AVACs heat and cool without the use of a fan, completely removing the presence of disruptive sounds. All of the acoustic absorption can be hidden within the panelling, and they are acoustically-designed to reduce noise and improve the reverberation time of the space.
More importantly, by selecting a multifunctional system which heats, cools and controls acoustics, the occupants’ comfort is not compromised. These systems distribute fresh air around a space, ensuring thermal and acoustic comfort, which is of particular significance to employee wellbeing and happiness. According to the World Health Organisation, it is estimated that the annual cost to Europe from excessive noise levels is £30 billion. This extortionate sum accounts for lost working days, healthcare costs and reduced productivity.
Acoustic control is a complete design necessity in commercial workspaces. Although exposed ceilings are perfect for new build and future retrofits and make maintenance easier, it is important to take all elements into consideration when planning an acoustically- sound space. In terms of air distribution products, there are sophisticated, multifunctional solutions available on the market which, simultaneously, control acoustics and heat and cool spaces. As commercial office spaces tend to be acoustically-demanding areas, flexible, state-of-art air distribution technologies should be a priority, particularly as they can assure thermal comfort without any unwanted background noise inconveniencing the occupants.
