Our new flagship instrument: the Bedrock AM100.
For those of you who knew we were working on this: we're sorry to have kept you waiting! But the final result will not disappoint. The Bedrock AM100 continues the development of easy-to-use and versatile measuring tools, progressing several steps at once. Its design, based on glass and alloy parts, is eye-catching as well as extremely durable. The 4" high-resolution capacitive touch display makes the device extremely easy to work with.
We added many new features, such as wireless connectivity (Bluetooth and Wifi), a second input channel, a headset jack and an internal signal generator. We also upgraded the specs in every possible way, from dynamic range to internal storage space and battery life.
We could talk about the AM100 for hours, but you should really see it for yourself - our distributors and dealers are happy to tell you all about this new product, and so is our This email address is being protected from spambots.

Acoustic calibrators are now added to our product line-up
Acoustic calibrators enable you, as a user of acoustic measuring instruments, to verify the level calibration of your instrument, and make adjustments if needed. It is considered "good laboratory practice" to do this before and after every measuring session. Even though are microphones are exceedingly stable, it is still a good idea to adopt this measure as a precaution.
We offer two product versions: BAC1 and BAC2 (respectively for class 1 and class 2 devices). The devices are easy to operate and require very little maintenance. Each device comes with a calibration certificate issued by an external accredited laboratory. The Bedrock BAC2 (class 2 version) comes complete with an adapter for our standard class 2 microphone (BAMT2).
Get the most out of the SMxx instruments with our MS Excel tools
As many of you will know, we offer a series of tools for importing data from the Bedrock SMxx instruments (SM30/SM50/SM90) into MS Excel. You will need a recent version of MS Excel (2010 or newer).
These import tools read multiple output files from the SM50 (STIPA, SLM and RTA mode) and convert these into a manageable table. You can also use the tools to easily browse through the measurements. The files can be downloaded here.
There are many different combinations of Excel versions, Windows versions and software that interacts with Excel. We've tested the tools on the most common combinations, but we can't rule out that some people might get unexpected results. So please review your data carefully when you first use these files. Unfortunately, for now, the tools usually do not work in Mac OSX (theoretically, as long as you have VB installed, it should work - but in practice this is not always the case).
Your feedback is as always appreciated; all bug reports are (as usual) gratefully received and used in future updates.
Firmware 2.6 now released. This is our biggest update yet!
Firmware version 2.6 for the SM30, SM50 and SM90 has been released. As always, the new firmware adds exciting new features to your instrument - and as always, it's free. Firmware 2.6 adds five completely new modules:
- THD+N (analyze distortion and noise in electro-acoustic systems)
- Frequency estimation (measure the fundamental frequency of complex waveforms)
- Insulation (measure airborne sound insulation in buildings according to ISO-16283, ISO-140 and ASTM E332)
- SRI/STC (measure the Sound Reduction Index R'w and the Sound Transmission Class; ISO-717 and ASTM E413)
- STIPA averaging: measure STIPA and average across multiple measurements
We also implemented improvements to various modules:
- The STIPA Pro and Full STI modules can now take background noise from any measurement, not just the last one.
- SEL (Sound Exposure Level) was added to all SLM modules (SPL, L%)
- The "impulse" time weighting was added to all SLM modules
- L% now also stores SEL,LMAX, LMIN and LEQ
- LAEQ logging module now also has the option to display C/Z-weighted levels
A few changes and additions apply to every module on the device (through system settings):
- Added "Delayed start" option
- Added"measure continuously" option
Also, as usual, we gladly incorporated feedback from users who pointed out minor glitches and inefficiencies in the user interface. We also fixed some minor bugs and enhanced the stability of the USB interface during transfer of large amounts of data.
To top it all of, we released updated versions of all of our Excel tools. An Excel tool for download and analysis is now available for every module on the SMxx.
The update package can be downloaded here (note that logging in is no longer required). The manual has also been updated. As always, the update is free for all existing and new owners of the Bedrock SMxx.
Your feedback and bug reports are (as usual) gratefully received and used towards future updates.
If standard devices don't cut it, simply get a Bedrock device customized!
The Bedrock philosophy is simple: anything we build is designed to be easily customized. Take our digital signal processor, the DSP500 series. Even the standard model comes with plenty of options. But since we've built this around our own signal processing chip, our BSP64, there's nothing you could think of that our team cannot make.
The Bedrock SM50: speech intelligibility meter, and more...
The Bedrock SM50 is the first Speech Transmission Index meter that has been completely developed and designed by the inventors of STIPA. The design is based on a simple philosophy: we wanted to create the best and most accurate STI measuring instrument there is, while making it very easy to use at the same time.
A unique measuring instrument
The SM50 is not only a Speech Transmission Index meter, but also a fully compliant class 2 / type 2 sound level meter (IEC 61672, ANSI S1.4) and a class 0 real-time analyzer (IEC-61260). Not to mention a RT60 meter, LAEQ logger and oscilloscope. Even seasoned acoustical engineers and audio professionals tell us that those features are really everything they need in their day-to-day work.
