Building Acoustics

Sound Insulation in Construction

Building acoustics deals with sound transmission from adjacent apartments and rooms (for example through human voices, impact sound or installation noise) as well as with sound transmission from outside (for example caused by road traffic or aircraft noise).

Even at the planning stage, the required or desired level of sound insulation for buildings can be addressed in precise detail. This helps to avoid planning errors that can result in high follow-up costs. In existing buildings, acoustic performance parameters can be determined by measurement and compared with applicable requirements and agreements.

As an accredited sound insulation testing centre under DIN 4109, Kramer Schalltechnik GmbH offers the following services in this field:

• Development of planning concepts for structural sound insulation
• Preparation and verification of sound insulation evidence in approval procedures
• Carrying out spot checks on sound insulation during construction
• Determination of "relevant" exterior noise levels and dimensioning of passive sound insulation measures
• Carrying out building-acoustic measurements of airborne and impact sound insulation in accordance with DIN EN ISO 140 and DIN EN ISO 16283, with evaluation according to DIN EN ISO 717
• Measurement and evaluation of noise from water installations, e.g. in accordance with DIN 52219, DIN EN ISO 10052 or DIN EN ISO 16032
• Development of acoustic improvement measures

Acoustic Investigations in Special Test Rooms

As part of our expert activities, we can also offer the following acoustic investigations:

• Acceptance testing of audiometry rooms and booths for air and bone conduction audiometry in accordance with DIN ISO 8253
• Acceptance testing or assessment of the suitability of anechoic rooms and semi-anechoic rooms in accordance with DIN EN ISO 3745
• Determination of sound power levels L_WA and absorption coefficients α_W in the reverberation room in accordance with DIN EN ISO 3741
