Description and 22 Customer Benefits

The Hyperdynamics Model 186 microphone measures from ordinary sounds to high intensity and or high pressure sound. It will also measure bomb explosive pressure pulse's or gun and rifle shock waves from
50 to 186+ decibels and shock pressure of 30 PSI(200.3 db)!. It has an extremely wide air pressure range. It is also wide frequency range and has the capacity to measure from an extremely low
1 hertz to over 20,000 hertz.

It is EXTREMELY rugged and totally airtight and hermetically sealed, so it is perfect for a variety of harsh or dirty environments, and pure pressure fields (perfect for CAR STEREO COMPETITIONS) or even totally underwater! Here are 2 photos of ocean abuse with no problems!

After all this violent ocean and car abuse, a small hairline half inch crack(glue able) in the case but amazing...



Seriously, would you ever want to try that with ANY other microphone?

The microphone itself is internally self-powered so it does not require separate power or battery supply.

Most microphones use weak diaphrams, this microphone uses a solid metal alloy block. This makes it basically impossible to puncture or rupture due to particle impacts, superhigh sound pressure level, accidental mishandling or near field shock waves.

The unit converts sound to an electric output voltage, so is meant to work with Digital Multi-Meters that read into MILLI-volt levels(even low cost WALMART $18 kind or a $500 Fluke the accuracy is still the same), oscilloscopes, computers and our computer software, and charge or voltage amplifiers.

NEW; now available in your favorite color: gold, chrome, silver, blue, red, green, pink, yellow, orange, purple including fluorescent neon: pink, orange, yellow. Please request color and add $29 extra or else we will ship standard black.

Here are 20 real performance advantages and benefits that make our meter better than "other" world class laboratory sound pressure level meters.

Our sound meter:

1. comes with a 100% money back guarantee

2. does NOT cost thousands of DOLLAR'$

3. it's easy for anyone to use

4. does not require complicated and expensive electronics to work. In fact the sensor microphone itself requires NO power, not even a battery!

5.We use REAL SOUND WAVES to test and calibrate each and every INDIVIDUAL meter!, not electronic or statistical tests like other companies and each and every one is calibrated TWICE on different days to increase accuracy range up to 0.01db to 0.05db! Furthermore


Nobody else does or even can...

6. does not use expensive and complicated wires or connectors to work. In fact if you wanted to, you could use ordinary speaker wire!

7.Each and every microphone comes with a paper calibration chart and computer software program that is calibrated to the United States National Institutes of Science and Technology (N.I.S.T.), and over 150 World Governments and International Standards

8. is extremely rugged, waterproof, and will survive accidental soccer ball treatment, or ocean/sea abuse, or even actually getting run over by your car!

9. can handle those INSANE VOLUME LEVELS without breaking or maxing out or distorting. (this meter is extremely tough). Lot's of peaple have been trying to max it out or break it, but can't, a superloud level was
178.5 db, like in the photo shown below of a 15" pro woofer, but with two of them facing each other and 11,000 watts of power, this was scary loud! But this was no problem for this microphone.

10. It also comes with a C.D. Computer Software #1 disk, which calculates the voltage to dB level for you;

Its also filled with the owners manual and instructions, lots of photos and files that are sound related including a sound pressure level decibel chart, for quick reference against all kinds of things like race cars, 40,000 watts of car stereo's, mosquitos, even bombs, shock waves and volcanos!

11.We wish we could describe how loud a sound this will measure. Sure some other meters are nice but you cant measure above 130-140 db with them before they max out, you could never shove them up the supersonic shock wave of a jackhammer, against a harley davidson motorcycle exhaust pipe, or even put them underwater like this meter, and they usually calibrate at a weak 94 db at 1000 hz.,

12. does not not require or need equalizers, frequency filters or wieghting systems

13.It also goes superdeep into the bass, you can measure with a digital millivolt meter or on an oscilloscope.Frequency way below 1 hz, see superlow frequency door openings at 1.8 to 4 hertz, wind and cold drafts, even fast barometric changes in the weather at 1 to 3 hertz at about 100 to 110 db, it is way cool.

14. With optional computer spectrum analyzer software #2 can handle the extreme sound range of the quiet level of 50 decibels to 186 decibels+ visually see the frequency range from 10 hertz to 50,000 hertz!+ the real time frequency and decibel level and peak levels.

15.Super powerful electric output in electric MILLIvolts so it can work with an ordinary digital MILLIvolt meter, D.M.M., oscilloscope, spectrum analyzer or computer. Milli-volt meters read out like: 0.013, 0.234, 0.985, 1.874, 2.438 volts ect.(there are 3 numbers to the right side of the decimal point). Expensive high quality or lower price and quality(like walmart) multimeters will work basically the same with the same readings (+-0.1 db)

16.Built in suction cups for fast and secure mounting on smooth surfaces like glass, especially in very intense vibration fields like jets or car stereo competitions.

17. NEW, now available in your favorite color: gold, chrome, silver, blue, red, green, pink, yellow, orange, purple including fluorescent neon: pink, orange, yellow.

18. Comes with C.D. Audio test disk for instant testing of your home entertainment, car audio system, or stadium concert system.

19.Handmade, to assure the highest quality...

20.Our microphones are OFFICIAL N.I.S.T. CALIBRATED. All N.I.S.T. calibrated pressure sensors/microphones will read the same db levels as ours including;
PCB, B+K, ENDEVCO, MIGGETT, KISTLER, OMEGA, QUEST, GRAS and the new TERM PRO/LAB db car stereo meter,
Just an example of 11 happy worldwide customers examples say "real world" decibel and dynamic pressure levels;
Customer 1 reports:"162.7term 161.9our"
Customer 2:"147.1 term 146.7 our"
3:"153.4 our 153.3 term"
4."156.6 our 156.6 term"
5."148.4 our 148.4 term"
6."138.4 our 138.3 term"
7."Great Product!! Only 0.2db different then my term lab"
8."Mic cal is real close to a termlab, works fine"
9."Shipping was quick, unit works great. Tested against a known SPL source A+"
10."Thanks a ton for a price effective alternative for a 1500.00 meter! Quick ship"
11."Completely awesome meter, finest on the planet, thanks a bunch!"

21.All our microphones have their calibration level clearly marked on them for anyone to easily read. No hidden computer files, key codes, internet registration, calibration factors, frequency weighting systems, or factory re-equalization that cause annoying doubts about accuracy. All OUR microphones are completely interchangeable with any other of OUR microphones ANYWHERE IN THE WORLD and they will all read the same db level! It doesn't even matter if they are on different computers or digital multimeters.

22. Extremely precise resolution db levels far above and beyond that of any other sound meter in the world! As an example you can see the difference between;
+-0.086 db from 130.000 to 130.086 db
+-0.006 db from 158.000 to 158.006 db
+-0.001 db from 175.000 to 175.001 db
These precision resolution levels are so high and powerful, you can actually see how even slight and tiny movements in your hands or body position can effect the db level of a sound, inside a car or out. In car stereo or home audio, this resolution means you can instantly see the effects of any tiny, microscopic changes you make to your audio system, or environment.Compared to any other mics AT ANY PRICE NO OTHER SOUND METER IN THE WORLD HAS OUR dB RESOLUTION LEVELS! All this with an ordinary digital multimeter!

23. FREE recalibration special, just send us your meter and 10 U.S. Dollars for return U.S.A. shipping or 20 for international shipping

24. although rated for 186db it will take shock wave pressure of 30 PSI(200.3 db) with no problem. 60 pounds per square inch PSI(206db), still functions good but may need calibration testing.

25. heres a little movie a customer made showing you how easy it is to use;

now just $299 U.S. Dollars,

Option #3
NEW! Specially calibrated microphone with Full Digital Meter Pre-Calibrated (Reads dB and frequency directly from Meter in digital numbers!!) the system and microphone is calibrated to 150.0db so it will read out -10.0db at 140.0db or +3.2db at 150+3.2=153.2db, another example 125.0db real life = -25.0db on the meter. in other words you still will have to add or subtract from 150.0db!!!, so 103.0db real life will say -47.0db. or 162.4db real will say +12.4db on this sound meter.lowest reading is -60.0db = 90.0db real life to 186.0db after a few minutes its very simple to use!!!the db level also measures directly voltage from almost any source, like voltage from a wall socket(0.001 volt to over 200 volts) it is true rms, fast responding about 3 to 4 times per second. with music resolves the bass frequencies about 3 to 5 times per second to 0.1 hertz, so it will say 22.4 hz, or 47.3hz, 62.1 hz ect. very cool!for frequency reading input electric volts must be at least 0.070volts, (70millivolts) when using microphone thats about a loud 120db or louder.
