Where were you sitting, and what phase of flight was the 115db reading? I agree that's very high, approaching pain threshold, but having spent more than my fair share of time on the JungleJet, I never found it to be remarkably noisy.

When you start the app up for the first time, there is a drop-down where you select the level of pocket lint caught in the microphone opening.

What do you think UA is going to do - they did manufacture nor certify the plane.

Just don't fly that route with that plane or choose another airline if it bothers you that much.

It all depends on where you sit on an EMB145. Toward the front is much louder and I always wear hearing protection when up there.

Jet engines are loud. If you're sensitive to the noise, the Bose QC35 is a particularly effective solution.

Though I seriously question the high end reading on that iPhone.

But does that requirement apply to flight crew?

I disagree... While my preferred seats on the 145 are 18A/D when I wind up in 1A it's almost frighteningly quiet as long as you aren't doing sonethiso like a rapid descent. Given the aft-miubted engines I'd expect that the further back the more engine noise you pick up.

For the OP, I work in an industry which requires very expensive equipment with yearly certification. Plenty of apps out there, but aren't certified. If some app on iPhone even remotely matched what the multi thousand dollar equipment did, these vendors would be out of business. I trust some app about as much as I trust FB ensuring my privacy.

iPhone sound pressure level meters are notoriously unreliable. (They CAN work, but are only accurate when paired with a properly calibrated external microphone--the internal microphone is virtually useless for this purpose.) Aircraft cabin noise levels are evaluated on a fairly regular basis--there have been a fair number of studies by OSHA, and all of them have found noise levels to be well within accepted parameters. There is a good summary of some of the findings here: https://www.gao.gov/assets/690/688396.pdf

It doesn't look like any of the studies referenced relate directly to the ERJ-145, but all aircraft manufacturers measure cabin sound to ensure OSHA compliance, and it's also notable that OSHA and the FAA have received a grand total of 2 noise-related complaints in the last 5 years.

It's possible that there was a mechanical issue that increased the noise level, but it's more likely that your iPhone app was just inaccurate (and there are a number of reasons why a normal noise level would cause more discomfort than usual).

OSHA's permissible levels are set for 8-hour exposure, day after day. I wouldn't want to spend 4 hours riding in the back of an E-145, to be sure.

I flew on a longer RJ145 flight a little over a year ago that I found uncomfortably loud enough that I also took our my phone and checked the SPL level and snapped a screen shot. My phone showed around 91-92 dB pretty consistently. It may not be a precise measurement, but I found it uncomfortably loud and my phone agreed that it was loud. I was in seat 18A on an ExpressJet UAX flight.
