Setting the Standard for Industry Specialists to Follow

For two generations, the Collman family has been involved in the creation and adaptation of key noise guidance & regulations. From the 1967 original BS4142, Method for Rating Industrial Noise Affecting Mixed Residential and Industrial Areas, which Richard Collman Sr. helped to create to the significantly changed 2014 edition of BS4142, renamed Methods for Rating and Assessing Industrial and Commercial Sound with which Richard Collman Jr was closely involved.

Since 1972, we have led the way in the acoustics industry. We always have been, and continue to be:

• Pioneers: in the use of consecutive logging of short duration sound level measurements rather than single long-term statistical values. When applied correctly, this now widely used technique provides far more detailed information about an acoustic environment, enabling better quality assessments to be produced, often at lower cost.
• Advocates: for the use of The Highest Suitable Noise Level^TM, which is now recognised in current Government planning policy to make acoustics sustainable. This overcomes the need to achieve an unnecessarily or unreasonably low noise level that provide no additional benefit.
• Leaders: The first independent noise control engineering organisation in the UK to use sound intensity measurement techniques as a diagnostic tool to investigate sources of sound.
• Forerunners: in sustainability, working to reduce foodstore delivery noise to enable night time deliveries without disturbing nearby residents and providing a wide range of Government recommended sustainable benefits.
• Experts: in measurement and analysis techniques, promoting the use of rolling statistical parameters to provide a much better understanding of the sound levels being measured.
