Trident’s basic operational mode is the sound level meter mode.

Trident’s FFT analyzer provides users with a high resolution, multi-channel FFT analyzer with graphical zoom and cursoring options.

Trident’s ISO 532B Loudness Analyzer conducts loudness analysis in parallel with the sound level meter and FFT analysis.

Trident’s calibrated time waveform recorder creates multi-channel calibrated audio WAV file recordings in parallel with the measurement functions of Trident.

Trident’s Reference Spectrum Feature is a powerful display tool that allows comparison of the current sound pressure levels to stored spectra.

Quick and easy export allows users to export their data into MSExcel spreadsheets or text files.

Trident’s sound intensity module operates in parallel with the sound level measurement features of Trident, allowing you to acquire both sound pressure levels and sound intensity levels simultaneously.

Trident’s Level versus Time module conducts reverberation time analysis for building acoustics applications.

The Trident Limit Analyzer feature is designed to support end of line product test and other Pass/Fail type measurement applications.

Sound Quality Analyzer provides several methods for achieving proper level calibration of WAV files, which is an inherently uncalibrated file format, but a convienient file format because there are so many ways to record and listen to WAV format files.

Sound Quality Analyzer conducts several sound level analysis functions on audio WAV format files.

Sound Quality Analyzer provides tools for listening to your audio WAV files while you view the analysis.

Sound Quality Analyzer conducts FFT (Fast Fourier Transform) and STFT (Short Time Fourier Transform) analysis on audio WAV format files.

Sound Quality Analyzer conducts psychoacoustic loudness analysis of audio WAV files. Loudness (sones) – A measure of the perceived sensation of the volume of a sound.  The loudness of the sound considers not only the level of the sound but the frequency composition of the sound.  Broadband sounds will have a lower loudness than narrowband […]

Sound Quality Analyzer conducts Sharpness analysis on audio WAV files.

Sound Quality Analyzer conducts Roughness analysis on audio WAV files.

Sound Quality Analyzer conducts Fluctuation Strength Analysis on audio WAV files.

Sound Quality Analyzer conducts Tonality Analysis on audio WAV files Tonality is the ratio of correlated energy to uncorrelated energy in a signal.

Sound Quality Analyzer conducts prominent tone anlysis per the Promince Ratio method as defined in industry standards such as ISO 7779 and ANSI S1.13.

Waveform Analyzer provides several methods for achieving proper level calibration of WAV and TDMS files, which is an inherently uncalibrated file format, but a convenient file format because there are so many ways to record and listen to WAV and TDMS format files.

WAV File Analyzer allows you to set your analysis parameter for sound level versus time analysis of audio WAV Files.

The Waveform Analyzer software provides sound pressure level vs time analysis over the user specified frequency range and time intervals.

Fitting Noise and Noise Source for Fixture Based Testing REATPlus provides pink, white and red noise signals for use as fitting noise for subjects, or as a noise source for fixture based testing according to ANSI S12.42.  Noise can be presented at a variety of levels to meet the current test needs.

REATPro provides complete user control over Stimulus Setup parameters and complete user control over Threshold Detection parameters.

REATPro uses the threshold detection settings from the configuration file to automatically determine hearing thresholds in both the Unoccluded and Occluded subject modes.  The stimulus is automatically presented as configured in the stimulus settings and the subject response state determines rather the next stimulus level increases, or decreases, for determination of hearing thresholds using the modified Bekesey audiometric method.

The medical alarm analyzer is designed to analyze WAV file recordings of medical alarm signals in accordance with the requirements of IEC 60610-1-8. 

Medical Alarm Analyzer conducts time waveform analysis on medical alarm signals for compliance with the requirements of IEC 60601-1-8

MAA conducts frequency analysis on alarm signals to insure the spectral content meets IEC 60601-1-8 standard for required harmonics in the signal.

For melodic alarms, the MAA software determines the frequency information of each note and compares it to a specific alarm melody dictated by IEC 60601-1-8.

Small Device Test Systems use Small Device Test Chambers to provide sound isolation of exterior sounds from the measurement of sound emissions of your device.

VIacoustics supplies Small Device Test Chambers from ETS-Lindgren as part of its standard and custom test systems for product noise emission measurement.Small Device Test Chambers are available in four standard sizes that address most small device measurement applications.
