02 Aug Halls Acoustic Enhancement
Facilities in general, especially learning ones, require a level of acoustics and sound absorption that facilitates clear communication and provide an enjoyable atmosphere whether the activity is a school assembly or one of the many sports which are carried out in these environments. Yet, sports facilities such as sports halls and gymnasiums are large open spaces built to withstand years of use for a variety of sports and they are built with hard wall, floor and ceiling surfaces making them particularly poor acoustically. The following are ways to enhance acoustic performance in sports facilities:
Actually, to control a sports hall’s acoustics, a large amount of acoustically absorptive material has to be applied around the hall for:
- Indoor sports halls and gymnasia differ substantially from other secondary rooms in that they are very much larger spaces intended in general for teaching groups of active students and as a result, they have a dramatically different acoustic environment.
- Although design criteria for the acoustics of indoor sports halls and gymnasia are part of current building regulations, in practice it has been difficult for designers to achieve these standards and accordingly sports halls are rated as the most difficult learning space to hear in.
- These spaces are often used for a variety of activities making their acoustic performance important in order to facilitate clear communication and provide an enjoyable atmosphere whether the activity is a school assembly or one of the many sports which are carried out in these environments.
- Acoustics in sports halls have to differ from regular building and ceiling acoustics.
- Sports hall acoustics are typically reverberant due to a combination of large areas of hard block walls, corrugated steel ceilings and wooden floors along with high ceilings and a spray-on material has a distinct advantage over acoustic panels in this situation.
Sound in a room will repeatedly bounce off surfaces such as the floor, walls, ceiling, windows or tables and reverberation of the sound reduces when the reflections hit surfaces that can absorb sound such as curtains, chairs and even people likewise:
- Once emitted from a source, sound waves in the hall travel through the air until they reach a boundary surface or other obstacle.
- When a sound wave reaches a surface, it will be partly reflected off the surface back into the hall and continue traveling in a new direction, and it will be partly absorbed by the surface with the absorbed energy being dissipated as heat.
- When these reflections mix, a phenomenon known as reverberation is created.
- Sports facilities are particularly problematic when it comes to echo and reverberation due to the hard wall, floor and ceiling surfaces which are required to withstand years of use from sporting activities.
- An important term we should talk about here is ‘’ reverberation time’’ and reverberation time is the time required for the sound to “fade away” or decay in a closed space.
- For newly built sports halls reverberation time must not exceed 1.5 seconds (or 2.0 seconds if 280-530 m2).
- For refurbished sports halls, reverberation time must not exceed 2.0 seconds, regardless of size.
With the soft, absorptive core sitting flush against the walls of sports halls and the panels having a naked backing, they are fully impact resistant and ideal for sports halls and gymnasiums with high impact activities for:
- Acoustic solutions for sports halls use acoustic panels that are sound absorbing panels that are hung on a wall or ceiling to control and reduce noise, eliminating slap echo in a room.
- The objective is to enhance the properties of sound by improving sound quality and soundproofing which concludes any means of reducing the sound pressure with respect to a specified sound source and receptor.
- The benefit of this solution is that you are able to choose almost any fabric you want to wrap the core with – giving you more design flexibility.
- These sound absorbing panels come in a large variety of sizes, types and colors to meet your design, budgetary, and durability requirements.
- Acoustic panels by timber acoustic panels provide an ideal solution to noise control in sports halls due to their ability to withstand high impact and resist damage.
- They can be easily installed to both wall and ceiling surfaces.
- The panels come in a range of colors, making it easy to match the color scheme of different sports halls and gymnasiums.
- Acoustics solutions in sports halls aim to facilitate good speech intelligibility and speaking conditions in teaching spaces, and to prevent interference by noise with study activities.
- There is also a health and safety benefit with the acoustic panel by -Panels as well, providing prevention of injuries from impact against walls during sport.
Ultimately, the appropriate cladding material to use depends on the orientation of your building and surrounding environment, whether it’s located in the city, beach, and the façade itself. Speaking to an architect and designer will play an important role in correct material selection as they’ll know the constraints of the materials and requirements.
Why don’t you favor OBRAS INTERNATIONAL to ensure a complete service package in a ventilated façade system in wood and fiber cement cladding. They also offer acoustic solutions for all kinds of projects that require a technical indoor conditioning and design.
Their products have defied intense heat, humidity and dry desert weather, as well as high-density snow and rainy areas in the mountains and their group of ace specialists has a noteworthy vision for craftsmanship and style that works perfectly when joined with the study plans. They propose plans, supply material, assist technically, supervise the work, and guarantee a quality finish.
