    Acoustics in swimming pool

    Acoustics in swimming pool

    Swimming Pools have one of the most difficult of environments to treat acoustically.  With hard tiled surfaces surrounding the pool mixed with the sound of people swimming, playing and shouting the noise can reach extreme levels.  Instructors of swimming lessons would find teaching very difficult alongside the poor swimming pool acoustics and the serious problem existed of misunderstanding the public address system announcements and instructions in the event of an emergency. Swimming pools & leisure centres should provide an acoustic environment that allows people to enjoy their leisure time in peace, within a safe environment regarding humidity moderator.

    Controlling Swimming Pool Acoustics

    The goal with your soundproofing treatment is to improve the sound quality by lowering your level of ambient echo. By reducing your background noise, you raise greater clarity to original sound and produce a more user-friendly swimming environment.   This is accomplished by introducing a set of sound panels for swimming pool acoustics that can effectively combine to capture and convert the unwanted echoes out of your room and deliver back the sound values you are seeking. Acoustic baffles can be wall or ceiling mounted inside your space.

    A Noise Reduction Coefficient is an average rating of how much sound an acoustic product can absorb. (How much quieter a product can make your space.) Like a sponge absorbs water, an acoustic product absorbs sound and the NRC tells us just how much sound those products can soak up.

    The Scale

    NRC ratings range from 0 to 1. An NRC of 0 means that the product absorbs no sound. An NRC of 1 means that the product absorbs all sound. The higher the NRC, the better the product is at soaking up sound

    The thickness and density of a product are two factors in calculating a Noise Reduction Coefficient. An acoustic product with a .95 NRC rating means that 95% of sound in the space is absorbed, while the other 5% is reflected.

    The acoustic panels with insulation materials which used within the construction structure are the ideal solution for absorbing sound in areas with large volumes such as swimming pools.

    Acoustima® acoustic panel by Seatup Turkey® has different types, shapes and colors of acoustic panels which are suitable for the swimming pool environment, These panels are used for both   noise reduction and moisture resistance.

    Acoustics in sports halls

    Acoustics in sports halls

    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. As a result, they have a dramatically different acoustic environment. Sports halls are rated as the most difficult learning space to hear in.   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. Sports Facilities such as sports halls and gymnasiums are large open spaces built to withstand years of use for a variety of sports. They are built with hard wall, floor and ceiling surfaces making them particularly poor acoustically. 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.

    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.  To control a sports halls acoustics, a large amount of acoustically absorptive material has to be applied around the hall.  A spray-on material has a distinct advantage over acoustic panels in this situation.

    An important term we should talk about here is ‘’ reverberation time’’ Reverberation time: is the time required for the sound to “fade away” or decay in a closed space. Sound in a room will repeatedly bounce off surfaces such as the floor, walls, ceiling, windows or tables.

    When these reflections mix, a phenomeon known as reverberation is created. Reverberation reduces when the reflections hit surfaces that can absorb sound such as curtains, chairs and even people.

    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.

    Reflection and Sound Absorption

    Once emitted from a source, sound waves in 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 travelling in a new direction, and it will be partly absorbed by the surface with the absorbed energy being dissipated as heat. 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.

    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. 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.

    Acoustic solutions for sports halls by using Acoustic panels Acoustima® acoustic panel by Seatup Turkey®  are sound absorbing panels that are hung on a wall or ceiling to control and reduce noise, eliminate 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.

    These sound absorbing panels come in a large variety of sizes, types and colours to meet your design, budgetary, and durability requirements.

    Acoustima® acoustic panel by Seatup Turkey® 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 colours, making it easy to match the colour scheme of different sports halls and gymnasiums.

    Acoustics solution 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 Acoustima® acoustic panel by Seatup Turkey® -Panels as well, providing prevention of injuries from impact against walls during sport.
