Acoustics in Indoor Stadiums

Acoustics in indoor stadiums is needed to improve the quality of sound and minimize noise in stadiums. Indoor stadiums are usually much bigger spaces than standard classrooms and since the reverberation time has relation to the volume of a room, the reverberation time will be longer if the room is larger without considerable noise control. There are recommended guidelines by BB93 for reverberation times and internal ambient noise levels but these are frequently stretched as far as possible, if not surpassed, because of costs involved with bigger scale acoustic treatment and other professional bodies have suggested alternative performance standards allowing for longer reverberation times.

BB93 Criteria

There is a requirement that sports halls on school sites under the Building Regulations to abide by BB93 with respect to reverberation time, sound insulation, and internal ambient noise levels. For indoor ambient noise, the BB93 criteria in these spaces is ≤40dBA with a reverberation time (Tmf) < 1.5 seconds. Criteria for other bodies are somewhat less strict with mid-frequency reverberation times between 1.5 and 2.0 seconds and the capability of sound insulation achieving a minimum of NR40 (≈45dBA).

Reverberation Times

It is important to have good acoustic design as long reverberation times can cause poor speech intelligibility, increased stress levels for the occupants, high background noise levels, and management/control difficulties. The greater the background noise the more the need to shout and currently sports teachers experience significantly more voice and throat problems than teachers of other subjects. When empirical formulas are used, care has to be taken for calculation of reverberation times inside spaces as large as auditoriums. Empirical formulas usually assume that in the entire space acoustically absorbent material distribution is uniform so calculating that, for instance, the reduction of reverberation time to 1.5 seconds by 800m2 of Class B absorbent material may not work in reality. It may be revealed in a sound test that in the case of flutter echoes there will be a higher reverberation time than expected between hard opposing untreated walls.

Acoustical Products used for Acoustics in Indoor Stadiums

The acoustical products Timber Acoustic Panels, Acoustics on-50 Steel Perforated Panels, Acoustic Baffles, and so on provide acoustics in various applications.

Timber Acoustic Panels are simple and easy to fix and remove. They can be got in many configurations. They can be used in schools, lobbies, offices, meeting rooms, halls, stadiums, hotels, and auditoriums.

Acoustics on-50 Steel Perforated Panels allow you in obtaining great sound reduction in combination with a tough operable steel finish that is durable. It can be used in machine rooms, factories, stadiums, workshops, test areas, and swimming pools.

Suspended Acoustic Baffles can be got in many standard types but also available in customized designs. Acoustic Baffles are suitable for reducing reverberation times in larger spaces like pools, gyms, stadiums, cafeteria, factories, churches, and large halls etc.

Using acoustical products for acoustics in indoor stadiums will make them a better place for conducting various events.
