While we are happy to visit you in your offices (our entire sales team is fully vaccinated and masked!), we recognize that many of our customers are not permitting external vendor visits. While we use online demos and seminars to great effect, we value face-to-face time with you, as it better enables us to truly understand your measurement needs and challenges.
We had a blast at our Fall roadshows in the San Jose area, and are planning further events on the West Coast in the Spring. Once the weather warms up, if Covid still prevents traditional visits, we’ll tour the East Coast and Midwest.
How it works
We schedule a day with you, where we will bring our truck and equipment and set up in your parking lot. We need permission to do this from the relevant people at your organization, and 3-4 parking spaces. Our vehicle is a large rental car, and we bring a pop-up table for demos. Depending on the event and weather conditions, we may also have a small (10’x10’) gazebo. We very much appreciate access to power and restrooms if available, although we can operate without it. We’ll bring giveaways, pre-packaged snacks, drinks and copious supplies of masks, hand sanitizer and wipes to disinfect the equipment after each touch.
In order to successfully plan, we need to schedule a date approximately 6-8 weeks in advance. This gives us time to plan a logical route, book flights and rentals, and promote the event.
To get on our schedule, or discuss further, please contact firstname.lastname@example.org or your local sales engineer.
How much space do you need? About 3-4 parking spaces. Our preferred spot is close to a building to facilitate power supply, but this is not critical – anywhere in your parking lot or building grounds could work. A small outdoor area with tables such as a patio or dining area also works well. The photos on this page are from one of our larger set-ups. We can be more compact if required.
How many people from Listen will attend? Likely 2 or 3
How long will you be here for? Our visit may last anything from a couple of hours to all day, depending on how many visitors we expect and what demos we are bringing.
Do you need power? It helps us immensely if we can run a power cord from your building, although we can run demos for a limited time period from the car battery if needed (we may need a jump start afterwards!)
Will you be noisy or disruptive? No – this isn’t a ‘party’ roadshow. There is no band, no amplified music, no entourage of trailers. Just 3 of us with a car and some audio measurement demos.
Do you need to come into our building? No. We are happy to meet in your building if it is permitted (we are all fully vaccinated, masked and follow Covid protocols responsibly). However, to minimize Covid risk, our entire event takes place outdoors. We appreciate, but do not require, bathroom access.
What are you doing about Covid Safety? Maintaining the entire event in the open air minimizes risk. Our entire visiting team is fully vaccinated and boosted. We wear masks and maintain social distance, and ask that attendees from your company do the same. We will provide hand sanitizer and disposable masks. All demo equipment will be cleaned with disinfecting wipes after each touch. Any food and drink offered is pre-packaged in single-serve portions. Please share any concerns or questions with us in order that they can be addressed.
What about crowds? This is not a crowded event. Usually people visit alone or in groups of 2-4 with other members of their team. We schedule meetings throughout the day to avoid congestion. Typically we have 20-30 visitors over the course of the day.
How will people know about the event? We will email the people we know at your organization. However, we greatly appreciate the assistance of your team leaders in sharing news about the event.
Interested in hosting us? Please contact email@example.com or your local sales engineer.
Visit us next week at our West Coast Audio Measurement Roadshow! We’re bringing our truck to various outdoor locations in the Bay area for Covid-safe product demos, previews, refreshments and giveaways (details below). If you haven’t received a personal invite yet, please let us know and we’ll send you full details!
This event has already taken place, but you can view the recording here.
May 27th, 2021. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time)
In this 1hr online seminar, Les Quindipan of Listen, Inc. and Kristopher Hett of Portland Tool & Die demonstrate how to test Bluetooth devices.
Kris Hett will introduce the Portland Tool & Die Bluetooth interfaces that are used to connect the device under test to the measurement system. He will discuss the technical specifications, and explain the differences between these and other types of Bluetooth interfaces. Les Quindipan will then demonstrate how these have been fully integrated into SoundCheck for simple plug and play operation, and how they can be used in test sequences. He will also highlight some of the algorithms included in SoundCheck that overcome Bluetooth-induced time delays, thus enabling these devices to be tested in a similar way to their wired counterparts. A complete test on a Bluetooth speaker and a Bluetooth Headset will be demonstrated.
There is no charge for this seminar, but registration is required.
Note: We are repeating this seminar in conjunction with our exclusive distributor in China, S&V Samford, on June 3rd at 10.00am China time. Please register for this seminar instead if this timing suits you better or you prefer the slides translated into Chinese.
In this 120 minute online seminar, S&V Samford presents Listen’s Technical Support Manager, Steve Tatarunis, discussing some of the more advanced aspects of microphone testing including:
- Substitution, Equalized Source and Transfer Function sequences in SoundCheck, including how to calibrate for these measurements. This is an expansion of material covered in the ‘basic microphone testing webinar’ and include more details about the sequences and calibration and the trade-offs of each method.
- Advanced measurements including polar plot, phase, self-noise, signal to noise, distortion, active/passive noise rejection
- Open loop microphone testing for voice activated devices such as smart speakers, automotive audio etc.
- Advanced hardware and test configurations for measuring microphone arrays and MEMS devices
There is no charge for this seminar, but registration is required.

Due to the current COVID-19 situation, we are not offering in-person group training classes. These will be resumed when regulations allow and there is the demand for it.
In the meantime, we offer customized online training for groups of people from the same company, and can offer flexibility in timing, session length and schedule. Please contact your sales engineer for more information.
Additionally, we will shortly be announcing some scheduled online training classes and these will be posted here as soon as information is available.
Don’t forget to check out our collection of Working from Home with SoundCheck videos on our Youtube channel. Our support team has created this series of videos that demonstrate features of SoundCheck that can easily be explored offline without full access to your lab.
If you are a new user, our series of on-demand training videos is a good place to start. These cover much of the content from day 1 of our basic 2 day training.
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.
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.
San Jose: Plaza Suites, Santa Clara.
Boston: Listen Offices. 580 Harrison Ave Ste 3W, Boston, MA 02118.
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.
