After more than a decade, I've finally made more *SimpleP48* mikes for my own use ... but found the passage of time hasn't been kind to my eyes. I found several errors and misleading info in my June

That's probable. Correct.

Thanks a lot Jerry. That answers my question. I was pretty convinced that using a tight coupling capacitor on the output (with cut-off at 30-40Hz) was helping the mic clip less. Deep low sounds like

I may not have been clear in my former answer. It's certainly true for passive dynamic and ribbon mics. Microphone designers design their products to operate within the context of existing equipment,

The quoted impedance of 2.2k is actually that of the supply resistor. The FET in the capsule operates in teh so-called "pentode region", which means that its actual impedance is very high, several

Dear mic experts, I'm trying to design a discrete amplifier for an electret capsule and have quite a technical question that is puzzling me. The device is a PUI AOM-5024L. I encountered the

No, not like the AKG D99. I used the ITU-T P.58 standard "HEAD AND TORSO SIMULATOR FOR TELEPHONOMETRY" as a design specification and took their drawing and made 3/4 inch slices through it. I cut them

That is a really lovely piece of work. I made a dummy head out of slices of wood about twenty years ago but it's not nearly as attractive. My slices were horizontal.

There is FLAC compression. Lossless. It reduced the size substantially.

Yes, the size matters. Making a bigger head will improve bass separation but will not reproduce acoustic panorama faithfully. The whole point of the dummy head is to reproduce acoustic character of

Hello, I've drafted up a DIY design that I think could work to drive an electret capsule like the TSB-2555B through the use of a DC-DC converter ( IEB0105S12 (

Microphones with "lobar" patterns use specific acoustic additions to achieve them. Typically multiple tubes or multiple tapped tubes. Capsules by themselves are 1st-order, ranging from omni to fig-8

Just about any curved "dish" shape will provide some focusing and gain. This article has some suggestions ( https://www.ehow.com/way_5569096_doityourself-parabolic-microphone.html ) for common items

Yes it will effect sound quality. But portability might be something to consider.Sent using Zoho Mail ---- On Thu,16 Nov 2023 23:00:41 -0500 clistburnham@... wrote ----Do the dimensions matter?

I suspect the lobar pattern comes more from the interference tube, not the capsule itself. (I’m definitely not an expert on shotgun mic design… but if it were possible to create a lobar pattern

Hi there - i was wondering if there are electret elements with lobar patterns. i'm not seeing any on a simple google search - and i'm curious about why that might be. Thanks!

Size matters. The larger, the better the bass respons will be. This is in direct relationship of the wavelength. E.g. the disc is 68cm diameter: frequencies above 500Hz will have a boost and high
