Have you Ever wondered how loud that annoying construction work outside your window is or how intense the vibrations from the latest dance track are? Sound Meter Pro, the prodigious fourth member of the Smart Tools® collection, has your back. And while they’re presenting an advanced version for your ears’ pleasure, they still give ample love to the original Sound Meter Pro. Now, let’s jump into what makes this app so darn fascinating.

A MASTERFUL TOOL FOR SOUND

Sound Meter Pro isn’t your ordinary SPL(sound pressure level) meter app. It doesn’t just randomly gauge the noise; it’s calibrated using a genuine sound meter with dB(A) on multiple Android devices. But, a head’s up! Most smartphone microphones are tweaked for human voice, between 300-3400Hz at 40-60dB. So, when your concert gets too rocking or that airhorn becomes too annoying, certain sounds beyond 100dB might elude its grasp. But this app is a reliable buddy for those everyday noises (40-70dB). And hey, devices like Moto G4, Galaxy S6, and Nexus 5 have been put to the test!

VIBROMETER: FEEL THE VIBES, LITERALLY!

Ah, vibrations! Sound Meter Pro’s Vibrometer feature is here to measure it all, whether it’s that rhythmic tapping of rain or the jolt from a minor earthquake. It is a rudimentary seism detector drawing data from your phone’s sensors. Are the values it churns out related to the Modified Mercalli Intensity scale (MMI) and worried about accuracy? Calibrate it, and you’re set. Remember, 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 cake? The Pro version! With it, you’re signing up for an ad-free experience. Sound Meter and Vibrometer become one, ensuring seamless measurement. Dive deep into your stats with the line chart feature, and for those who love their data in spreadsheets, there’s CSV file exporting. And as if that wasn’t enough, there’s an extended line-chart duration and more calibrated models to ensure precision.

KEEP THE CHANGE, IT’S A ONE-TIME DEAL

Breathe easy, dear users. Sound Meter Pro doesn’t drain your wallet with sneaky recurring charges. Make a single payment, and the app’s all 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 make sure you’ve opened it a couple of times while connected to Wi-Fi or 3G/4G after installing.
