We will be exhibiting at ISEAT in Shenzhen on Nov 14-15, 2105. On display will be our SoundCheck audio test system and associated hardware for testing a range of audio devices including speakers, microspeakers, headphones, microphones, smartphones, tablets and more.
Listen president, Steve Temme, will also be presenting a technical paper with Sean Olive entitled “The correlation between distortion audibility and listener preference in headphones.”
We will be exhibiting at the 139th AES which will be held at the Javits Center, New York, NY on Oct 29-Nov 1, 2015.
At our booth (#242) we will be demonstrating the latest release of the SoundCheck software, version 14, and the new SoundCheck 14.1 for Mac, as well as showcasing our entire audio test hardware lineup including the new AudioConnect audio interface and BTC-4148 bluetooth interface. We will be demonstrating how you can test virtually any type of audio or audio electronic device with the SoundCheck test system, and showing off some of the latest features of our software.
Steve Temme will also be co-presenting a paper entitled ‘Headphone Response: Target Equalization Trade-offs and Limitations’ with Christopher Struck of CJS Labs. This paper is first up in the P4-1 session (Transducers, Part 1) at 2.30pm on October 29th. In this paper, the effects of headphone response and equalization are examined with respect to the influence on perceived sound quality. Free field, diffuse field, and hybrid real sound field targets are shown and objective response data for a number of commercially available headphones are studied and compared. Irregular responses are examined to determine the source of response anomalies, whether these can successfully be equalized and what the limitations are. The goal is to develop a robust process for evaluating and appropriately equalizing headphone responses to a psychoacoustically valid target and to understand the constraints.
The new BQC-4148 Bluetooth interface is designed for high volume production line testing of Bluetooth sink devices such as headsets, speakers and car kits. It offers control over the CODEC choice, sample rate, and transmitter power, enabling devices to be specifically tested under the conditions that they need to operate
The unit is rugged and compact, measuring just 30 x 64 x 136mm. With only one connector – a USB for connection to the computer for power and control – it is simple to use and offers minimal potential for incorrect operation. It can be controlled via the USB virtual com port using a command line utility, or from within SoundCheck using the control utility via a system step for simple integration with your test sequences. Although it is less full-featured than its R&D counterpart, the BTC-4148, it is approximately half the cost.
Classes will be held in our Boston offices on September 21-23, and in the San Jose area on Oct 5-7. Both sessions will follow the same format, beginning with a 1-day course on electroacoustics testing, presented by Chris Struck of CJS Labs. In this useful class you will learn about the theory behind your audio measurements. The content will cover sound level measurement, psychoacoustics, electroacoustics, soundfields in real rooms, frequency responses, test signals and more. It is ideal for those new to the industry or anyone wishing to gain a better understanding of the measurement principles behind their acoustic tests.
The 2nd and 3rd day will be our 2 day SoundCheck training class. This covers all the major features of SoundCheck version 14, including writing sequences, test signals, analysis, distortion measurements and more. The class is a combination of presentations interspersed with hands-on exercises to ensure that you are comfortable with all the concepts and methods taught before you leave the classroom. Although no previous SoundCheck experience is assumed, the course still offers plenty to users familiar with writing basic sequences. Although the SoundCheck training is intended as a 2-day program, it is possible to attend just one day of the training. We are working on finalizing venues, but please put the dates in your diary, and we’ll have more information soon.

Al has spent the majority of his professional career in the audio industry, designing award-winning products and managing product development teams. Al’s career began at Sony Professional Products, where his designs included mic preamps and equalizers for the MXP-3000 mixing console. He then spent many years at Lexicon, where his technical contributions can be found in several effects processors. When Lexicon entered the consumer marketplace with digital surround sound processors, Al not only made design contributions to these products, but also established the development team and helped round out the Lexicon product line with multi-channel amplifiers and DVD players. After their acquisition by Harman, Al led a highly skilled team that designed Mark Levinson products, including several critically acclaimed amplifiers. After spending four years in the solar industry, where he managed development of high-power inverters, Al is returning to his audio roots and passion, and is excited about leading the development of cutting-edge audio and electroacoustic test and measurement products at Listen, Inc.
In this short (10 minute) video, Brian Fallon introduces the new features in SoundCheck 14. These include an improved set-up wizard for easier transition from older versions, advanced Listen hardware integration, a redesigned hardware editor and a new autoranging feature.
Listen Inc is proud to announce its 20th year as a leading provider of audio test and measurement systems and expertise. Two decades of innovation and steady growth have made Listen’s flagship product, SoundCheck, an industry-standard audio test system in the consumer electronics industry.
The company is commemorating the occasion with updated branding – a new, more modern, logo and a new website, www.listeninc.com.
Listen began operations in 1995 when a consulting client of Steve Temme, company founder and president, challenged him to build a computer-based system with the same capabilities as the hardware system that they currently owned. This challenge came with a promise that if Steve could produce the system within 6 months he would buy it. Steve met the challenge, the product was named ‘SoundCheck’, and the customer purchased 12 systems. Steve then began to further develop the product to meet the test requirements of a wider audience.
Although the first generation of SoundCheck was designed specifically for testing military headsets, the next version was designed with a very open architecture which allowed virtually any audio device to be tested. It is this open architecture which has, in part, led to Listen’s success as the system has inherently been able to adapt to the changing test requirements of the audio industry over the past 2 decades. For example, in the 1990’s, SoundCheck was primarily used for testing loudspeaker and microphones, but today its most common applications are testing headphones, microspeakers, smartphones, tablets and Bluetooth devices.
Although Listen has its roots firmly in software, today Listen also offers turnkey systems with a complete line of audio test hardware. Designed from the ground up, Listen’s hardware products are engineered to specifically meet the needs of the audio test industry, thus making them reliable, simple to use and cost effective, as well as tightly integrated with Listen’s software.
Listen is still owned and managed by Steve Temme, and is headquartered in an 8000 square foot facility in the South End of Boston, within a mile of where the company started 20 years ago. Listen also has sales and application engineers on the West Coast, and a worldwide sales and support network. Listen is still growing steadily, and has several open positions in both engineering and sales.
“We at Listen, Inc. are thankful to our many customers for making this anniversary possible,” said Steve Temme, president of Listen, Inc. “Their feedback has driven product development and helped us evolve as a company. We look forward to continuing to innovate with our products and test methods, and to serving our valued customers for many years to come.”

We are excited to announce a 1-day SoundCheck® Advanced Training Seminar on Monday, June 1st 2015.
This new training class covers a combination of advanced electroacoustics education and SoundCheck topics that are beyond the scope of our basic 2-day training course. It is of broad interest to most testing applications, although the open loop testing is particularly relevant to smartphone, tablet and other devices which do not have an audio path between test system and device.
In celebration of our (and SoundCheck’s) 20th anniversary this year, we are offering this course at 1995 prices – just $199!
Places are limited, so sign up early.
