Application of WinAudioMLs in building acoustics
The demand for powerful measurement solution in building acoustics is
growing.
With WinAudioMLS you can perform the following measurements
 |
level analysis with octave or 1/3 octave resolution |
|
attenuation of e.g. walls or windows |
|
long-term measurements and logging for e.g. traffic noise |
|
reverberation time |
|
room impulse response |
|
energy decay plot |
WinAudioMLS makes measurements easy with the following features
|
display of all measurements in real-time |
|
weighting of two microphones |
|
can be calibrated |
|
weighting with 'A' or 'C' curve |
|
averaging |
|
peak hold |
|
measurements results can be easily transferred to your reports |
Maximum-Length-Sequences (MLS) in building acoustics
Traditionally technician use pink noise for measurements. If you want to
measure e.g. walls with high attenuation it is difficult to reach sufficient
signal to noise ratio, without using high transmission power or excessive
averaging.
With the sophisticated MLS-technique together with modern digital signal
processing
algorithms, measurements are more efficient. The gain is typical 20-30dB.
|
higher signal to noise ratio (more accurate) |
|
lower signal levels |
|
less averaging required (faster) |
|
only smaller amplifiers and loudspeakers required (portable) |
