In acoustic measurements (SPL, frequency response, noise, reverberation, etc.), large errors often come not from instrument accuracy, but from a mismatch between the assumed sound field and the actual one. What a microphone reads as sound pressure is not strictly equivalent across different fields-especially at mid and high frequencies, where the microphone dimensions become comparable [...]
How do CRYSOUND measurement microphones and calibrators perform when independently tested against established reference equipment-and pushed beyond typical laboratory conditions? In the September 2026 issue of audioXpress, technology consultant and long-time audio equipment designer Stuart Yaniger conducted a hands-on review of three CRYSOUND products: The review covered calibration accuracy, frequency response, environmental stability, self-noise, ruggedness, and [...]
We are excited to introduce the newest addition to our product portfolio - the CRY3000 Series Measurement Microphones, a groundbreaking lineup designed to set new standards in precision and versatility for acoustic measurement. Engineered for a wide range of applications, these measurement microphones deliver unparalleled performance and durability, making them the ideal choice for R&D, [...]
In multichannel acoustic testing, entering microphone model numbers, sensitivities, and calibration data one channel at a time is slow and prone to error. TEDS allows a data acquisition system to read key parameters stored in a microphone or preamplifier, helping engineers configure channels faster and maintain consistent test settings. This article tests the CRYSOUND CRY3203-S01 [...]
In day-to-day acoustic measurements, it's common to hear: "Insert the measurement microphone into the calibrator, press the button, and the microphone is calibrated." From an engineering and metrology perspective, that wording is an oversimplification. To place a sound calibrator correctly in the measurement chain, we should start with what it generates-and what it can (and [...]
