Default Will this mic be any good for measuring?

Hi

Would a Shure SM58 be any good for taking measurements? It is the only mic in the media loan centre(free) of my university and therefore the only one I can get my hands on. I do realise it's a vocal mic, but surely it's better than nothing and should give a reasonably accurate response?

It's the first time I've tried taking measurements, so just looking for a bit of advice.

Thanks

Have just realised it only has a freq response from 50-15000hz. Didn't realise that would be the case.

Right, not a good choice. The SM58 has a bass roll off that will make it seem you are getting no bass in your measurements. The top end isn't great, either.

Better to buy a Panasonic mic capsule than use the 58.

So if I were to build that little mic unit would I need any form of amplifier? It would be simply connected into my laptops 'mic in' socket. I have limited free time and money, so cheap as possible and glad you've pointed me to this little Panny mic.

Go to Linkwitz Lab - Loudspeaker Design and navigate to microphone in the projects section. Some good advice there! E

It needs power, about 5V. Some mic connectors supply that. I don't know on your laptop.

I thought so. I am trying to get on the Linkwitz site, but it won't seem to load at the moment for me.

This will work nicely with the mic input on your notebook:
