Turnkey Acoustic Contracting
Absol International LLC can provide you turnkey design and Install Services for the variety of Acoustic jobs, be it auditoriums, plant rooms, genset rooms, environmental noise controls, studios and cinema's etc. We have a extensive design capabilities in these fields some of which are listed below but are not limited to:
Acoustic Design and Noise Control in Architecture Absol International can advise on all aspects of the acoustic design of commercial, public, industrial and residential buildings, covering control of noise from mechanical services and other installed equipment; insulation of the building shell against the ingress of external noise and the egress of internal noise; sound insulation within the building and optimizing acoustic conditions within specific rooms or spaces.
In the case of a large building development, for example, Absol International would carry out an environmental noise survey to establish the prevailing noise climate and anticipate relevant changes from traffic or other forecasts; set suitable noise criteria for the various spaces; specify attenuation requirements for the ventilation system; determine the sound insulation and vibration isolation needed for machinery spaces; specify sound insulation requirements for the building envelope; advise on room layout and partitioning to achieve the required levels of privacy, and deal with all details of the acoustic design of rooms. Absol International is therefore able to undertake responsibility for all aspects of the acoustic design of buildings. If required, these services will include supervision of the installation of noise and vibration control equipment and testing on commissioning of the building. In the case of dwellings such testing would include the measurement and appraisal of sound insulation for the purposes of Building Regulations approval.
Absol International can undertake the acoustic design of auditoria for music and speech such as concert halls, recital rooms, theatres, multipurpose spaces, lecture theatres and studios to optimise the conditions in accordance with the intended usage. The aspects covered may include the essential isolation of the auditorium from external noise and vibration, control of noise from mechanical services and design of the auditorium size, shape and finishes to achieve the required reverberation time and sound propagation characteristics.
Absol International services in the field of auditorium acoustics extend to the design of electro-acoustic systems for special applications, in particular low-frequency reverberation enhancement systems.
Absol International offers a design, specification and commissioning service for specialised electro-acoustic systems. Such systems are custom designed, thereby permitting a high degree of flexibility with regard to both ergonomic and aesthetic requirements, whilst achieving a careful balance between technical excellence and economy. Absol International is fully equipped in designing and supervising the installation of high quality speech reinforcement systems for Churches and Cathedrals. Of particular interest is the range of loudspeakers, designed to direct high quality sound down to the congregation without the need to angle the loudspeaker away from the supporting wall or column. Combining technical ingenuity with functional design ensures an unobtrusive appearance, which can be of great importance in avoiding the disruption of fine architectural lines within Churches and Cathedrals.
Noise from and within Industry Absol International is frequently asked to advice on the control of noise both from and within factories and other industrial premises in order to ensure the minimum risk of damage to employees' hearing or annoyance to the local community.This might typically involve measurement surveys,remedial design and the management of the ensuing noise control program in existing factories or expert assistance with the design of new factories in order to satisfy the relevant Statutory Instruments and Codes of Practice associated with The Health and Safety at Work Act, the Noise at Work Regulations and the Control of Pollution Act.
Absol International can carry out detailed noise surveys to identify the level of risk involved and to provide guidance and advice detailing the measures that should be taken by an employer to effectively protect the exposed workforce.
PERFORMING ARTS VENUES
Absol International focus on natural sound and vibration comes to fruition in the design of performing arts venues. All aspects of the acoustics,including technologically demanding work like scale modeling and building isolation, are handled in-house.Our team brings a higher level of scientific capacity to acoustic design, tempered by years of experience and an intuitive insight as performers and musicians.
The acoustical design of cinematic theatres entails the sound isolation of the theatres from exterior noise, and from adjacent theatres,acoustic design of the room, and evaluation of the HVAC design with respect to noise generation. Our services in this area include:
Computer modeling of rooms to determine all acoustic parameters including reverberation time,early decay times (EDT),and sound pressure level. This analysis can also be used to evaluate some acoustic anomalies within the room.
We provide detailed mechanical system design criteria early on in a project, so that the mechanical engineer can include these considerations early in the design. We then evaluate the system after it is designed to calculate noise levels within the theatre.
With modern digital sound systems, the evaluation of wall design between theatres is critical.The design of the wall itself is only one part of the entire process. Structure borne sound transmission through floors and sidewalls must also be evaluated. Exterior and interior wall designs are evaluated and CAD designs provided to the architect.
