There's a business idea. Noise cancelling so good you can listen to tunes while you're jackhammering.
I've never used a jack hammer. What is your line of work called? Paver? Masoner?
About 130 decibels is normal so it would need to be next level metal to cut through that!
I’m a semi-skilled contractor and mainly help out on small residential projects job-to-job.
