Loudspeaker Testing - Simple & Reliable like never before

Loudspeaker Testing - Simple & Reliable like never before
Testing your loudspeakers, transducers or subassemblies has never been easier. Just connect your device under test (DUT) directly to your FX100 Audio Analyzer and begin measuring. No more hassle with external amplifiers, cable dangle or measuring errors due to uncalibrated gain. The new integrated FX-SIP module with its powerful amplifier offers unrivalled performance, reliability and ease-of-use.

Octave and one-third octave band measurements with the FX100 Audio Analyzer

Octave and one-third octave band measurements with the FX100 Audio Analyzer
Octave and one-third octave band representations of measurements are widely used for real-time acoustic spectral analysis (RTA) in sound level meters. Audio Analyzers, on the other hand, typically represent spectrums with high-resolution FFT's. There are also audio measurement applications where standards require octave or one-third octave band measurements. NTi Audio provides a tool to derive octave and one-third octave band results from FFT measurement results using the FX100 Audio analyzer.

Low Frequency Noise – the XL2 now offers a valuable Toolbox for effective Assessment

Low Frequency Noise – the XL2 now offers a valuable Toolbox for effective Assessment
The Data Explorer PC software for the XL2 Sound Level Meter now includes a series of professional tools for detailed analysis of low-frequency noise (LFN). The graphical representation of time varying frequency components offers an efficient process for identifying the presence and level of LFN. Also the associated high quality audio recording supports further correlation with the objective measurement data.

Easy testing of Class-D Amplifiers

Easy testing of Class-D Amplifiers

Class-D (or switching) amplifiers are popular, not only because of their light weight, but mainly because they are highly efficient, with less power distributed as heat. Their audio parameters, however, can be difficult to measure because of high-frequency noise produced at the output stage. NTi Audio solves this by filtering out these unwanted noise components with the FX100 Audio Analyzer plug-in module filter, providing reliable test measurement of class-D amplifiers.

Top Class but cost efficient Solution for Electro-acoustic Quality Control

Top Class but cost efficient Solution for Electro-acoustic Quality Control
It is common to find electro-acoustic components, such as speakers, buzzers and microphones, in a variety of products like washing machines, freezers, vacuum cleaners and cars. On the production line, these components should be tested as part of the Quality Control process. NTi Audio provides the XL2 Audio and Acoustic Analyzer as a top-class entry-level QC test solution that produces reliable results every time. This solution can equally test the sound of mechanical components such as drills, where product quality decisions are based on the frequencies of the mechanical sound produced.

STIPA celebrates its 10th birthday at NTi Audio

STIPA celebrates its 10th birthday at NTi Audio

It has been 10 years since NTi Audio introduced STIPA for Speech Intelligibility measurements to their handheld instruments. In this time it has grown to become the accepted industry standard, and the NTi Audio Solution has become the most-used STIPA system in the world. As STIPA now enters its second decade, let us reflect on the early years and how the process evolved through active interaction with international standards committees.
