Hyperdynamics vs Termlab Sensor, The results are in!!

[shizzzon 461]

The Termlab is the official meter for most comps around the country but it costs close to 700 and most individuals sigh away from the price.

Hyperdynamics meter through ebay costs less than 100 but retails for around 350. They claim their meter is stricter than the Termlab, slightly (0.1-2.0db lower than Termlab between Db ranges of 120-170). Db ranges 171-180 have been noted to post upwards of almost 9 Db lower than Termlab.

This meter also goes up to 230Db accurate whereas the Termlab goes to 180 accurate.

Hyperdynamics is used to test explosions, bombs, shotgun blast, etc...

The reading methods are very different as well.

Termlab- Just hookup to laptop and watch your score LIVE!!

Hyperdynamics- hookup O-scope to meter to read out the active milliVolt reading. Once that is obtained, you input the mV reading into this small program that is ran on any windows based computer and it will tell you what you "hit."

A little more complicated, definitely not sufficient for competition sanctions but for personal use and over 600 percent cheaper... Definitely worth it.

The debate has been for over a year that no meter is as good or stricter than the Termlab and is cheaper... That cheaper!

Until now...

snoopdan was kind enough to travel out my way to do this test. Much thanks for snoopdan.

Ok, what we did was we held both meters beside each other and played 42hz tone for about 10-15 seconds.

The results @ 42Hz-

Termlab - 143.0dB

Hyperdynamics - 141.909214 or 141.9

When i had opened my door while turning it down the Termlab shot up to 144.7 hehe.

Well, Apparently Hyperdynamics was right!

The meter I use is more strict than the Termlab. So what does that mean?

This means that if you had this meter and used it to see how high you would "hit", expect a higher score in the judging lanes.

True it is a little more complicated to setup but once it's ready... It's a nice alternative.

The loudest i've ever done in this car with my current setup is a 145.513... who knows maybe it was close to a 147 on the Tlab??

WTF have you been! welcome back..

i was wondering when you were gonna be able to do a stright up test..

good job...

but lets be honest is money wasent an issure you would get a termlab right?

[shizzzon 461]

If money wasn't an issue?

The only reason why I would say Yes is because that is "the meter" everyone knows. When you want to compare with the rest of the world, why not use what the rest of the world is using?

However, for me, that's different.

It may be fun to burp your setup every once in a while but i am in no way turned on by being a member of any sanctioned audio competition. It just doesn't interest me. Electronic modding\repair and computer work is what i like best and i stick to it. That's who i am.

When i got this meter, based upon what i knew, it was going to be used to help me setup a design the best for my money. It did that. I had no intentions on comparing.

Also, because it reads lower, it's interesting to note that you could use this meter to "force" yourself to reach a goal in competition so when you actually went, you would be a lot louder!

It's safer to carry around though!

With a Termlab, you have to have the meter AND a laptop (usually). You don't want to keep a laptop in your ride at all times.

I do carry my meter with me just as i carry other test tools with me. This HD meter only requires an o-scope or a very good DMM capable of reading mV. Carrything those items around isn't that bad. Of course you may not know what you did until you get to a computer but i dont meter every other day either. I may meter a couple times a year, if that.

And yea, i've been gone a while but i'm back... I'll be back again for a while because i'm tearin down and redoin a setup in my scion tc.

the goal is to break 150.0 tuned for a musical daily driver... I have ideas

[jonbearsmt 919]

your right about alor of that....

termlab 1000 bucks.

laptop 300

keep it in my car... NEVER

its also kind of a pain in the ass to set up.. any my whole car shakes i can not use my hood nor my truck so set the lab and the laptop i need a table or someones ride.

redo it already... lol i know whatcha mean its like heroin allways chasin that dragon...

i just did a new box, went active.. with some hiccups, and changed all new cells....

good luck on your goal!

termlab connected to a car-puter connected to a flip-down tv or indash tv... that would be sweeet!!!

[slim2fattycake 85]

Man, I'm kind of mad I didn't get to go see ghetto set-up. Did you two run any other tests?

Bigjon, I think he had the idea to change when he found out snoopdan was running 5000 watts daily to his RE SX subs or that he knows I am going to be louder when I get my set-up ready.

Sean, when did you decide to go with a bandpass design?

[fritosaregood 0]

arent o-scopes pretty expensive themselves?

[3stagevtec 2]

anyone have a link for the Hyperdynamics meter?? 1st time i hearing about it.. sounds great for the price..

[3stagevtec 2]

found it..

so.....what do u think ...is it worth buyin ?

[Adrian_D 520]

Excellent result

People might have to consider this as an option.

By the way, what o-scope are you using ?

[shizzzon 461]

I am using the velleman off of partsexpress.

I believe it's the hps-10

We already compared that question?

That was the whole point to the topic.

The TL will read higher. The Hyperdynamics sensor is stiffer than the Tlab so to answer your question, the Tlab would probably read around 142.5-143 and the port would probably have read around 158.5-163db.
