iSTI, our Speech Transmission Index measuring software for iPhone and iPod, is now available in 3 different editions: Professional, Standard and Lite. Each edition is programmed and validated by the same core team that has been developing the Speech Transmission Index itself for the last few decades. Finally, there is a STIPA measuring tool for every budget!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.
Real-time analyser module for the Bedrock SM50 released
We are pleased with the warm reception our Bedrock SM50 STIPA measuring instrument has received since its introduction late last year. As promised, we will be regularly expanding its capabilities. The first major addition to the device's capabilities is that we've now added a Real-Time Analyser (RTA). New units ship with the RTA module included, the upgrade to firmware version 1.2 (which includes the RTA) is also free for existing users.
This is the first hardware instrument brought to you by the very team that developed STIPA.
Read all about the SM50 on our Bedrock product website. To name a few of the highlights:
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.
