Hi amigos, Before starting, I suspended the measurements of the first project "Micro Bamboo." I will come back to the quick...

As much as I know not, you need stand alone one (apps aren't really accurate) to enter SPL level and calibrate that part. After that of...

UMIK-1 is advantageous in that being a UAC1 device, it has no HW volume control capabilities. When used with the ASIO or Wasapi Shared...

Yes, this true and very helpful for the UMIk-1. No mixer HW. You can adjust the gain with some DIP switches on the PCB. But then you...

To make reliable SPL measurements (not relative frequency response or RT60) you will typically need a sound level calibrator. Some...

There exist some more sophisticated techniques for high SPL up to 180dB :) With coupled tubes for details...

Currently I'm using something similar. a 2" high power pressure driver with a 3D printed chamber. My refernce mic is a 1/4" MK301E from...

First, I’d like to thank you, @achimago for disassembling APX555. Very cool and interesting. Therefore, no need to disassemble my APX555...

Here are calibrated selfnoise measurments from an MM2. The microphone was acoustically shielded 1/3 octave measurment and the FFT...

all these simple measurment mics, use capsules with a typical sensitiviy of 12mV/Pa with an SPL of 133dB RMS you get an input voltage of...

Yes, I'm the owner of www.akulap.de www.dr-jordan-design.de www.akustik-messen.de akulap.de serves as a shop for all kind of article...

Unfortunatly, I do not know of a reliable sound source that can can handle these levels at low distortion. You want to measure the...

Hello, the cheap Omnitronic mic has significant USB Chirping see background of usb chirping In addition, I created a lot of articles...
