What is Reddit's opinion of Cadrim Decibel Meter - Digital Sound Level Meter, Self-Calibration Decibel Reader, Noise Meter with LCD Display Measurement Range 40-130 dB spl Meter (Battery Included)…?

From 3.5 billion Reddit comments

The primary concern is wind noise. I would want to take readings while traveling down the road to measure what my noise exposure is. They do not post dB reduction ratings as there is a lot that goes into it, such as what type of windshield you have, what the weather is like, current speed, if you wear a neck scarf etc.

I thought decibels was a static form of measurement, so I would just put a sensor in the helmet and it would give me a current decibel reading. Is that not correct? Idk what the calibration stuff is.

Basically I want one of these Cadrim Decibel Meter - Digital Sound Level Meter, Self-Calibration Decibel Reader, Noise Meter with LCD Display Measurement Range 40-130 dB spl Meter (Battery Included) https://www.amazon.com/dp/B07YZLZTCF/ref=cm_sw_r_apan_glt_fabc_3W284A88FTQJDM0GE243?_encoding=UTF8&psc=1

But with the microphone on a cable. (I could fit a decent size mic, so that is less of a problem, its the cable mic feature I need.

It can roughly measure decibels. Emphasis on 'roughly'.

It's limited by three big factors:

1) It's the wrong tool for the job. The microphone on your phone isn't built for that. No one is paying extra to have a phone that can precisely measure decibels. You would need a decibel meter to do that.

2) The instrument isn't calibrated. Every decibel meter needs to be calibrated periodically against a known sound from a controlled source, and I'll guess that you probably haven't done that, or have any way of doing that.

3) After a certain volume, the microphones on your phone stop receiving sound. They just electronically can't do it. That makes sense from a practical perspective -- why would anyone pay extra for a phone that can pick up deafening noise?! -- but it does severely limit the upper capacity on decibel reader apps. Your phone simply can't process sound louder than that.
