The dynamic range of a measurement microphone describes the span of sound pressure levels it can measure effectively, from weak sounds near the noise floor to high levels near the distortion or overload limit. In practice, the usable range depends on the microphone, preamplifier, data acquisition system, and test environment. Understanding Measurement Microphone Dynamic Range [...]

Measurement microphone sensitivity is usually expressed in mV/Pa. It describes the voltage a microphone produces for a given sound-pressure input. Sensitivity affects weak-signal output, sound-pressure conversion, and how the microphone matches the rest of the measurement chain, but a higher value is not automatically better. Understanding Measurement Microphone Sensitivity Microphone sensitivity describes the ability of [...]

Dynamic range, noise floor, and input range describe different limits of a data acquisition system. Input range sets the maximum measurable signal, input-referred noise constrains the minimum resolvable signal, and dynamic range expresses the span between them. This article explains how to compare these specifications under consistent measurement conditions. In the specification sheets of data [...]

Professional audio interfaces, audio analyzers, and data acquisition systems can all capture signals, but they are designed for different measurement tasks. This guide compares their interfaces, measurement capabilities, synchronization, sensor support, and typical applications so engineers can choose the right platform for each test. Scope Definition: In this article, a data acquisition system refers to [...]

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 [...]
