Noise/Sound insulation

 

 

Unwanted noise is a problem in many domestic and commercial buildings, particularly those in urban environments, or period properties with original single glazing. Traffic noise, street noise, noise from aircraft; all can adversely affect living and working environments, causing unwanted stress, a lack of concentration and worse.

Guidance and regulations

 

OSound is measured as a pressure and expressed in dB (decibels), where to the human ear a change of 3dB is just about noticeable. An increase in pressure levels to 10dB approximates to a doubling of loudness.

 

UK Guidelines include:

 

  • BS 8233:1999 'sound insulation and noise reduction for buildings'
  • Planning and policy Guidance 24: planning and noise
  • Building Bulletin 93: Acoustic design in schools
  • the WHO (World Health Organisation) 'Guidelines for Community noise' revised 1999 provides recommendations for inclusion in national guidelines

 

Reasonable noise levels at a glance:

 

Room Noise level
Bedrooms 30 - 35 dB
Music rooms 30 - 35 dB
Living rooms 30 - 40 dB
Classrooms/meeting rooms 35 - 40 dB
Librarys 35 - 40 dB
Open office 45 - 50 dB

The Glass

 

Different types and thicknesses of glass in the secondary windows are specified to achieve the best noise insulation, dependent upon both the volume & the type of the outside noise.
