The Reverberation Time Software BZ-7227 enables the B&K 2250 to make Reverberation Time (RT) measurements.

Press the Start button, clap your hands and that's all it takes to do a basic measurement in small rooms. The traffic lights shows measurement status at a glance, and the resulting RT spectrum is shown as well as the average RT, reverberation time for the room. Alternatively for large spaces use the built-in noise generator plus an amplifier speaker system.

Keep track of measurement positions in the colour map display, check the indicators for measurement quality, and add spoken or text comments to positions or projects.

Measurements comply with the relevant parts of BS EN ISO 3382 and other Standards.
