For the sake of completeness, here is another plot showing the responses for the NTi M2230: [IMG] For some designs the pressure and diffuse...
Excluding the housing from the measurement procedure would minimize the effects mentioned above, for sure. But on the other hand you would...
Looking at the graphs from hifi-selbstbau.de who measured more than 1000 cheap microphone samples I would say that most are not designed to...
Hey there, is anyone of you using compensation curves to address the boundary effects inside acoustic couplers like the 60318-4? [IMG] Source:...
I see. You mentioned it as "2703". That's why I couldn't find it. :D The 2730 is indeed very similar to the Primo EM258. I have no experience with...
Sadly, there is no official measurement to verify. Earthworks themselve don't publish THD graphs and I couldn't find any other reports examining...
The rule of thumb estimates a THD increase by three times every 10 dB. However, looking at some "real world" examples there is always a certain...
That is some interesting stuff, thanks for the links! That's what I speculated on the past few days, comparing data sheets, reviews and...
Another necro, please forgive me! Has anyone seen distortion graphs for the reference pressure microphones used in the dummy heads by B&K, GRAS...
Tbh, they look like toys. :D How do you imagine the mounting and sealing with the dummy head?
I did some digging and found the answer in the following resources: Presentation of the GRAS seminar at ALMA 2017 Abstract of the IEC 60318-4:...
Hey there, does anyone know what parts of the human ear the 711 coupler (60318-4 Occluded Ear Simulator) does actually simulate? Is it the ear...
Picked up the POP ears from the customs today. Here you can see them next to the other models:...
I will report :D Pulled the trigger yesterday. 80 AUD with free shipping seemed fair to me.
What do you think about those? [IMG] POP Microphones - Pair of Silicone Ears
My pair arrived today. The ears aren't perfectly symmetrical, indeed. Also the material is quite stiff. If I member it correctly, the humar ear...
Hi guys, I hope you forgive the necroposting. May I ask whether the project is still alive? I found your thread yesterday evening, browsing for...
