Building Acoustics
Our truly portable (5kg) battery powered SoundCam BIONIC is a game-changer in building acoustics:
locates sources down to 40Hz
Shows noise transmission paths and transmission loss across all octave bands LIVE on-screen
Shows sound leakage due to poor sealing
Shows sources and propagation of structural thermal expansion noises through buildings
Locates sources and transmission paths from building services (heating, AC etc.)
Shows location of wind induced noises on building exteriors

Locating thermal stresses in a concrete block of flats
SoundCam used to locate the source of annoying thermal stress cracking. Before we arrived the owners could not even tell which side of the building it might be. We located it right down to a joint between the floor halves of the balcony. A second video shows it looking down at the floor. This is filmed and calculated at 100fps but slowed down to 0.25 speed so you don't miss it.

Balcony thermal stresses found with SoundCam
SoundCam used to locate the source of annoying thermal stress cracking. Before we arrived the owners could not even tell which side of the building it might be. We located it right down to a joint between the floor halves of the balcony. This second video shows it looking down at the floor. This is filmed and calculated at 100fps but slowed down to 0.25 speed so you don't miss it.
Sound Leaks into/out of cubicle
Using the SoundCam ULTRA and an ultrasonic source outside the cubicle, we can easily see the poor sealing causing sound transmission in both directions.
Visualise Transmission Loss!
With a pink noise source in the far room we can easily see the weakest areas of transmission loss in each octave or third octave band. The random noise must be averaged to show all frequencies, so the acoustic picture is averaged over 10 seconds.
So now you can not only measure the sound insulation you can instantly find the weak points in each band.
