Measurement microphones, preamplifiers, intensity probes and the calibration chain that makes them defensible. The value is in the traceability, not in the part.
A more stable reference than an electroacoustic calibrator.
The full vector: the direction of the source, not just its magnitude.
Today it is copied out by hand, and nobody really does it.
Probe for in-situ measurement of the sound absorption of materials, on the principle of SoniCat-type probes. It characterises a surface where it stands, instead of cutting a sample and sending it to a laboratory.
Permanent installation, rodents, foot traffic.
A full day of autonomy without carrying a UPS.
Calibrate non-standard capsules without improvising couplings.
Knowing which instrument expires in 40 days before it expires on site.
The residual phase error check the standard asks for.
Use the capsule you own with the preamplifier you own.
The part that breaks first and costs as much as a microphone.
Mandatory before and after every measurement. Already in block A-bis.
A 60-second check that saves a whole campaign from being disputed.
Check the electrical chain with the capsule out of the picture.
Connect a measurement microphone to any audio interface.
The market reference costs ten times that.
The rustle from a cable moving in the wind, solved.
Not just the 1 kHz point: the whole curve.
Absorption and intensity in the near field, where p-p does not reach.
The heart of the intensity probe: two capsules with certified phase.
Sound level calibrator for checking the meter before a measurement. It is the step nobody skips, and the object nobody wants to find they left at the office.
The distance between the capsules sets the usable band.
Contact measurements on facades and floors, without a diffuse field.
Gaps, ducts, cavities and wall voids.
