2250 & 2270 Based Building Acoustics System

Building Acoustics Defined

Building Acoustics is the assessment of sound insulation in buildings and building elements. It is important for the well-being of people in their homes, workplace or public venues, and minimum standards are set in the building regulations of each country.

The assessment is based on measured 1/3 octave or 1/1 octave spectra within the 50 - 5000 Hz range. Measurements are carried out in real time (all bands simultaneously).

Tasks

There are three kinds of BA measurement (Tasks), depending on the purpose:

Airborne sound insulation is the sound insulation from one room (the source room) to another (the receiving room). It is calculated from the Leq spectrum for the average source room level L1, average receiving room level L2, receiving room background noise level B2 and average reverberation time T2.
Facade sound insulation is airborne sound insulation with the "source room" being the space outside a building, and the receiving room being inside the building
Impact Sound Level is the sound level in the receiving room from a standardized tapping machine in the source room.

Building Acoustics measurement with Type 2250 & Type 2270

Application software Type BZ-7228 is available for Hand-held Analyzers Type 2250 and Type 2270 . It provides the flexibility, ease of use and confidence in your results that field measurements require in building acoustics.

Back at the office, Qualifier Type 7830 offers versatile post-processing and reporting of your measurement results.

Dual Channel Measurement with 2270 & BZ 7229

Application software Type BZ 7229 is the dual channel measurement application for the 2270 hand-held analyzer and offers a time saving benefit in being able to measure in the source and receiving rooms simultaneously for airborne tests or outside and inside for facade measurements.
