VR Mobile vs Sound Level Meter

VR Mobile connects to any Vibration Research hardware device for live vibration test monitoring via an iPhone or iPad. It also contains engineering calculators, a light strobe, a noise SPL meter, and an accelerometer--all from your mobile device! FEATURES: Connect to the ObserVR1000 dynamic signal analyzer and data acquisition (DAQ) device - Set up inputs and record & monitor data - Live FFT Analysis - Use your mobile device's camera to record video in sync with your ObserVR1000 and/or GoPro® camera(s) Remotely control vibration tests running in the VibrationVIEW software - Start/stop tests - View graphs - Adjust amplitude and frequency VR Library - Complete courses, take quizzes and earn certificates on VR University - Browse articles, case studies, engineering tools, research papers, and more - Watch video tips and tech talks - Gain access to VR product manuals Max acceleration calculator - Calculate the maximum acceleration a shaker can output based on system mass Unit converter - Convert acceleration, force, mass, velocity, displacement, and more Sine calculator - Calculate acceleration, frequency, velocity, and displacement based on sinusoidal motion Shock calculator - Select the impact type (plastic or elastic) and the pulse type, and the shock calculator will calculate the remaining two values given two inputs: acceleration, impact time, velocity change, and height change Noise meter - Measure the minimum, current, and maximum decibels (dB) from your mobile device's microphone Accelerometer - Measure the minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes - Zero-out acceleration to calibrate for an uneven surface Strobe light - Strobe your device's screen and/or flash LED from 1 to 30 Hz; strobing helps display objects vibrating too fast for the eye to see VR products - View VR's vibration test controllers and dynamic signal analyzers - Watch YouTube videos from VR - Visit VR's website - Browse VR's LinkedIn page

Sonom turns your iPhone into a professional-grade sound level meter. See real-time decibel readings, track your daily noise dose, and get alerts when sound levels threaten your hearing — all without keeping the app open. REAL-TIME SOUND MEASUREMENT - Accurate dB readings with a clear, color-coded gauge - A-weighted (dBA), C-weighted (dBC), and Z-weighted (dBZ) modes - Fast and Slow response times for different measurement scenarios - Min, Average, and Max tracking for every session DAILY NOISE DOSE TRACKING - Monitors cumulative noise exposure based on NIOSH criteria - Shows remaining safe exposure time at any dB level - Weekly dose history chart to spot patterns - Syncs exposure data to Apple Health ALWAYS-ON MONITORING - Background audio monitoring — works with screen locked - Live Activity on Lock Screen and Dynamic Island - Noise alerts when levels exceed your chosen threshold - No need to keep the app open RECORDING & REPORTS - Save measurement sessions with timestamped readings - Generate detailed PDF reports for compliance or personal records - Review session history with peak, average, and duration stats PROFESSIONAL CALIBRATION - Guided quiet-room calibration for accurate readings - Manual offset adjustment for advanced users - Save multiple calibration profiles for different environments Built for anyone who cares about their hearing — from musicians and construction workers to parents monitoring nursery noise levels.
