Ever wondered how loud that pesky construction noise outside your window really is, or how intense the beats from the latest dance track are? Enter Sound Meter Pro, the impressive fourth addition to the Smart Tools® collection. While they’re offering an advanced version for your auditory delight, the original Sound Meter Pro still receives plenty of love. Let's dive into what makes this app so incredibly fascinating.

A MASTERFUL TOOL FOR SOUND

Sound Meter Pro is not your typical SPL (sound pressure level) meter app. It doesn’t just haphazardly measure noise; it’s calibrated with a genuine sound meter using dB(A) on various Android devices. Heads up! Most smartphone microphones are optimized for human voices, ranging from 300-3400Hz at 40-60dB. So, if your concert gets too wild or that airhorn too irritating, sounds exceeding 100dB might escape its detection. But for everyday noises (40-70dB), this app is a dependable companion. And yes, devices like Moto G4, Galaxy S6, and Nexus 5 have been tested!

VIBROMETER: FEEL THE VIBES, LITERALLY!

Ah, vibrations! The Vibrometer feature of Sound Meter Pro measures everything, from the rhythmic patter of rain to the tremors of a minor earthquake. It acts as a basic seism detector, using your phone's sensors. Worried about accuracy with the Modified Mercalli Intensity scale (MMI)? Just calibrate it, and you're good to go. Keep in mind that each Android device is unique, so using the results as a reference is always wise.

FEATURES GALORE WITH THE PRO VERSION

What’s the cherry on top of this acoustic masterpiece? The Pro version! With it, you get an ad-free experience. Sound Meter and Vibrometer combine for seamless measurement. Dive into your stats with the line chart feature, and for data enthusiasts, there’s CSV file exporting. Plus, enjoy an extended line-chart duration and more calibrated models for accuracy.

KEEP THE CHANGE, IT'S A ONE-TIME DEAL

Relax, dear users. Sound Meter Pro won’t hit you with sneaky recurring charges. Make a single payment, and the app is yours. Forever. Think of it as buying a coffee, but this coffee app stays hot and functional indefinitely.

A RESOURCEFUL COMPANION WITHOUT THE NEED FOR INTERNET

Sound Meter Pro’s generosity knows no bounds. No internet? No problem! You can start the app without any connection. Just ensure you’ve opened it a few times while connected to Wi-Fi or 3G/4G after installing.
