Acoustics is one of the oldest branches of physics. It originated in the study of music, which probably began with Pythagoras more than 2,500 years ago. By means of a single stretched string, he showed that consonant intervals in music can be expressed by ratios of simple whole numbers. Acoustics has come a long way since then, both as an independent branch of physics (physical acoustics) and in association with other sciences and arts. Acoustics first became associated with architecture when men began to assemble in groups to hear speeches, listen to music and see and hear plays.

  • Architectural Acoustics

    Architectural Acoustics

    Architectural acoustics refers to the science of noise control within buildings. The first application of architectural acoustics was in the design of opera houses, followed by concert halls. Noise suppression plays a significant and critical part in the design of multi-unit dwellings and business premises that generate significant noise, including music venues such as lounges, discotheques. Architectural acoustics includes room acoustics, the design of music studios, home theaters, and listening rooms for media playback.
  • Industrial Noise Control

    Industrial Noise Control

    Industrial noise control refers to the control of acoustic noise in industrial situations, especially noises that might exceed the human noise safety levels. For noise control at industrial sites, important considerations are prevention of hearing loss developed over time, speech audibility and communication interference, and becoming a general nuisance to surroundings.
  • Noise Monitoring

    Noise Monitoring

    Noise monitoring, assessments and surveys are required for a wide variety of activities ranging from engineering works to light manufacturing and even office / laboratory based environments. Commonly, only a small segment of the activities pose as a risk to health and thus proper set up of simple safeguards and working practices can resolve any potential problems caused by elevated noise levels. Noise monitoring will determine the most suitable method to reduce exposure of noise and enable the selection of the most suitable protection or insulation where necessary.
