Flexus FX100 Audio Analyzer

Anechoic Acoustic Measurements in a Reverberant Environment

The FX100 Audio Analyzer supports anechoic acoustic measurements under reverberant conditions. This feature delivers free-field frequency response results, even in suboptimal acoustical environments. The test is performed with a logarithmic GlideSweep.

Editable Time Window Masks out Unwanted Reflections

The room reflections can be excluded from the measurement results by introducing a time-window to the signal processing. A comfortable wizard in the FX-Control PC-software allows localizing the reflections in an impulse-response or energy-time curve (ETC) display. The time-window can then be graphically placed in front of the reflections, thus feeding the measurement algorithm with the direct sound signal only. The influence of the time-window to the frequency response becomes visible in real time.



Application Example

Frequency Response of a Speaker (measured with reflections from walls and ceiling):

Measured Impulse Response:

Manually removing reflections from the walls and ceiling:

Resulting actual Frequency Response of the Speaker (without any room reflections):
