11.30-12.30: Consultation time: Bring us your audio devices and your measurement challenges and we’ll discuss your measurement options and demonstrate how your devices can be measured

Note: there will be live demonstrations on all topics, and a display of hardware for a complete measurement chain including fixtures, measurement microphones and sensors, audio interfaces and turntable.

Detailed Content Information

Perceptual Distortion Measurements: Perceptual distortion measurements enable production line yield to be increased by rejecting only devices with audible Rub & Buzz defects rather than any distortion defects, and Listen’s new enhanced Perceptual Rub & Buzz (ePRB) algorithm is the first to perform even better than the human ear! Through proprietary noise reduction technology and advanced perceptual algorithms, its performance in a noisy factory environment is comparable to the performance of a trained listener under normal listening conditions. Learn more about the science behind this algorithm, see the results, and learn how to implement it in your end-of-line tests.

Accurate Headphone Measurements in Real World Conditions: In this demo-focused session, we will demonstrate how to accurately measure Headphones and Hearing Assistance Devices under real world conditions with real world signals such as speech and music. For example, we will demonstrate, in real time, how to adjust the headphone fit for a proper seal on the head and torso simulator and measure headphone ANC with real background noise with our Multi Signal Real Time Analyzer

New Features in SoundCheck: The newly released SoundCheck 20 is at the forefront of audio measurement with new features for multichannel and communications, increasing its capabilities for audio measurement of smart speakers, infotainment systems, headphones and hearables, and other voice-activated and multichannel devices. In this 30 minute session, we will demonstrate the new features and explain how they are used for testing a variety of audio products and applications.

Free-field Speaker Measurements without an anechoic chamber: Can’t afford or get time in an anechoic chamber? That’s not a problem if you have SoundCheck! In this practical session, we will demonstrate a method first developed by Listen president Steve Temme back in 1993, known as the ‘splice’ technique. This measurement technique is easy to configure and enables you to make highly accurate free-field measurements in an ordinary room, avoiding the expense of an anechoic chamber and enabling measurements in your home or office.

SoundCheck® 20 offers new features for multi-channel and room acoustics, as well as many usability upgrades including:

  • Enhanced Perceptual Rub & Buzz: Our new Perceptual Rub & Buzz algorithm is a reliable and repeatable method of detecting audible Rub & Buzz faults on the production line, increasing yield by rejecting only devices with audible distortion defects.
  • New Multichannel RTA functionality: The multichannel Real Time Analyzer now displays multiple channels simultaneously, and offers real time calculation and display of channel addition, subtraction, maximum, minimum and power average.
  • Updated Signal Generator: A complete overhaul of the signal generator brings additional functionality and simplified operation, particularly when using wav files.
  • POLQA: The optional POLQA (Perceptual Objective Listening Quality Analysis) module brings POLQA analysis right into SoundCheck, for perceptual measurements of speech degradation in communications applications ranging from telephones to smart devices.
  • Batch Processing of external files: External data files can now be batch-loaded and processed. This enables testing of a large number of external data files to be automated via a sequence, for example wav files of speech recordings.
  • New Features for Communications Testing: New stimulus steps and post-processing capabilities such as a silence stimulus step, and RMS level versus time and histogram post-processing steps support communications testing needs, for example, measurement of Doubletalk and other speech transmission parameters.
  • Stimulus editor upgrade: The stimulus editor can now create a stimulus from any waveform in the memory list and equalize and adjust its level, for example using active speech level. This enables such adjustments to be made to externally acquired test signals, such as those imported into SoundCheck via TCP/IP or recall steps.
  • Saving Multichannel Wav files: It is now possible to export multiple SoundCheck recorded waveforms to a single multichannel wav file.

Virtual Instruments Seminar

April 12th, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)

Virtual instruments, included in SoundCheck,  are a cost-effective and portable software-based alternative to hardware instrumentation, ideal for making quick measurements or viewing device behavior in real time. In this educational seminar, Les Quindipan walks through a demonstration of the virtual instruments in SoundCheck, showing off some of their lesser-known capabilities. These include the signal generator, multimeter, oscilloscope/spectrum analyzer, real time analyzer, frequency counter and distortion analyzer. The strip chart recorder, which expands the capability of these instruments to record measurements over a period of time, will also be discussed.

Note: We will be repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford. A sign-up link will be available shortly.

Measuring Hearing Protection Devices to ANSI S3.19-1974 Standard

This sequence is used to measure the NRR, or Noise Reduction Rating, of a hearing protection device to the ANSI S3.19-1974 standard. NRR is a numerical representation of the sound attenuation of a device. The sequence first measures the response spectrum of the unoccluded hearing protector test fixture, then makes a second measurement with the hearing protection DUT affixed. A signal generator virtual instrument generates the pink noise stimulus while an RTA virtual instrument simultaneously records the A and C weighted noise spectrums. The unoccluded and occluded measurements are analyzed with a series of post-processing steps according to the ANSI S3.19-1974 standard. The final display shows the NRR numerical value, RTA spectra of the left and right side of the unoccluded and occluded hearing test fixture, average attenuation level of the DUT, and the standard deviation of the DUT on the test fixture.

SoundCheck 19 New Features Video

In this short video, sales engineer Les Quindipan gives a brief overview and demonstration of the new features and functionality of SoundCheck 19, including the multichannel RTA, RT60 Room Acoustics module, AmpConnect 621 control, and more.

Huge Discounts on SoundCheck 19 Upgrades

For a limited time we are offering deep discounts on a system upgrade to enable you to get up to date with the latest version of SoundCheck. The upgrade offer is a simple flat rate: $3,950 for owners of SoundCheck 13 or 14, $3,250 for owners of version 15, $2,500 for owners of versions 16 through 17, and $1,395 for owners of version 18. All the modules on your present system will be included.

SoundCheck® 19 offers new features for multi-channel and room acoustics, as well as many usability upgrades including:

  • Multichannel RTA: The single-channel RTA is replaced with a new multi-channel version, which enables viewing of multiple signal paths simultaneously for a convenient view of many measurements across a wide range of applications. Spectrum settings are configured independently for each channel for complete measurement flexibility.
  • Room Acoustics RT60 (optional module): This module offers extremely fast and accurate measurement of the reverberation time and clarity of any room or space with calibrated signal paths.
  • WASAPI-Exclusive Mode: SoundCheck can now operate in WASAPI-exclusive mode. This delivers lower latency, ensures that sample rate conversion from the built-in Windows audio engine will not occur, and enables SoundCheck to ‘lock’ the audio interface to avoid measurement disruption by system sounds.
  • AmpConnect 621 Control: SoundCheck 19 supports AmpConnect 621, Listen’s new high resolution multichannel audio interface. Set-up and configuration is extremely simple and fast with full plug-and-play functionality and TEDS support for automatic identification, configuration and calibration of microphones and accelerometers.
  • Diagnostic Window: Warning dialog windows can now be suppressed when running a sequence, instead logging the errors, warnings, and information in a separate diagnostic window. This avoids sequence interruption by dialog windows in unattended or highly automated situations.
  • USB Controller Knob Compatibility: SoundCheck communicates with the Drok USB Controller Knob to simulate the feel of a manual analog signal generator. Used in conjunction with other virtual instruments such as the RTA, spectrum analyzer and distortion meter, this offers a rapid way to identify defects by observing the response while manually fine-tuning the signal generator.

 

Call your sales engineer today to receive a quote for upgrading all your SoundCheck systems. These discounted rates are only available until May 31, 2021, so please get your order in soon!
