How to lower SPL by 30 - 40 dB

Hi all, I am not sure if this is the right place to ask, but I want to take a shot: I have a circuit with small silicon microphone that has acoustic overload at 128db, however environment where I am going to monitor sound can get louder than that so I need to reliable lower incoming sound pressure by approximately 30db, kind of like putting protective headphones over ears when you do constructi

Help gaining SPL. Tips or tricks appreciated

Hi Guys, I'm new to these forums and trying to think outside the box and any suggestions would be appreciated. I own a car audio shop in Sydney Australia and compete in DB Drag Racing SPL competition. I know this is not the correct forum but your knowledge of sound pressure behavior is maybe at a higher level or different than in the car audio industry.

SPL for live shows?

I've been drafted to do the sound for a few live gigs of a band I've been working with in the studio. I have nearly no experience or training with live sound.

I've got a few questions to that extent.

1. What SPL should I be aiming at? I know that 97dB is safe for 30 minutes at a time, which is the approximate legnth of a set they're doing.

Recording at High SPL (Heavy Guitar), with a Condenser Mic

I'm going to be tracking some Heavy Guitars for a project I'm working on, and I want to use a condenser on the guitar cab. But I'm a little worried that this will damage my condenser Mic. I plan on using a Studio Projects C3 along with an SM57.

I was wondering if there is anyway to measure SPL so I know if it's safe to use my C3 at close range on the Guitar Cab.
