The Bedrock SM50 is the most reliable and most advanced STIPA measuring instrument on the market. In fact, it is much more - the SM50 is an allround acoustic measuring instrument featuring all the usual measuring functions, such as a fully compliant class 2 sound level meter and a real-time analyser. The Bedrock BTB65 TalkBox, an alround acoustic signal generator, is its ideal companion for STIPA testing as well as…More...
Embedded Acoustics is committed to sparking innovation in the fields of acoustics, speech and hearing. Our mission is to translate scientific knowledge and high-tech engineering into working, real life products and services. We're not just talk - get in touch and find out what we are all about: expertise, experience and a practical mindset.
White paper: measuring STIPA in practice
Speech Transmission Index measurements are now widely accepted as a rigorous and validated way to determine speech intelligibility. STIPA measuring tools such as our own Bedrock SM50 are used ever more widely - also be people new to acoustic testing and to the Speech Transmission Index concept. Although STIPA is thoroughly documented, through standards as well as a vast body of scientific papers, the current documentation is not easily accessible.
We just wrote a new white paper to assist newcomers in getting started with STIPA. More seasoned users may also find the white paper useful. It fills the gap between the pragmatic level of the user manual and the abstract level of our scientific publications.
Calibrated audio recording for the Bedrock SM50 released
We have just released firmware version 1.4 for the Bedrock SM50. New units now ship with this version. The new firmware supports recording of calibrated audio in all measurement modules. For one thing, this feature is great to preserve a fully intact audit trail of all your measurements: you can always redo your analysis on the actual data collected. This also allows the user to make calibrated recordings for offline processing by any other kind of acoustics analysis software.
The SLM module now also supports LCpeak. Know bugs and issues were fixed, and the manual was expanded and improved.
This is the first hardware instrument brought to you by the very team that developed STIPA.

ADIOS: Acoustic Detection and Identification of Drones
Embedded Acoustics was awarded a phase 1 SBIR grant to investigate the feasibility of drone detection by means of acoustic sensors. We will study passive detection (based on statistical pattern recognition on microphone signals) as well as active detection (measuring reflections of ultrasonic wave front). This feasibility study is scheduled to be completed by March 2015.
Embedded Acoustics wins "Veiligheids innovatie Competitie 2014"
We are very proud to announce that we have won the "Veiligheids Innovatie Competitie" (Security Innovation Competition)! This contest was jointly organised by the Netherlands Ministry of Defence and the Ministry of Security and Justice. Companies (in particular SME's) were challenged to come up with highly innovative concepts of new products and services for the Netherlands security regions. Nearly 60 companies initially registered interest in participation, of which approx. 30 submitted a proposal. Five finalists were selected from these proposals. The finals took place on Friday 14 November. The finalists pitched their proposals to a distinguished jury, consisting of high-ranking officials representing all relevant stakeholders.
The concept introduced by Embedded Acoustics is called "personal data recorder," or PDR. The PDR is a small, lightweight device, to be worn by first responders, that continuously records audio, video, GPS location and other sensor data. Data from the PDR serves as objective evidence against individuals committing acts of violence against first responders, which (unfortunately) is a major issue these days. Also, PDR data can be used to quickly and accurately determine the sequence of events in the aftermath of incidents and crises.
The prize is a contract worth €200,000. The prize money will be used to further develop the concept, making prototypes suitable for operational testing available by the end of 2015.
Acoustics consulting staff now offshore qualified
Embedded Acoustics is known to apply its knowledge to technical consulting projects in a wide variety of application fields, ranging from trains to airplanes, and from road tunnels to concert halls. We are proud to announce that we have now extended our scope to offshore activities. Embedded Acoustics staff have acquired the necessary certificates for working on offshore platforms anywhere in the North Sea region (NOGEPA, OPITO, OLF).
Services offered to the offshore sector include all types of acoustic measurements, including speech intelligibility measurements for verification and evaluation of evacuation systems and general announcement systems.
