Mac Tools vs Vibration Meter, seismograph

The Mac Tools SmartEAR2 Sound & Vibration Detection app was developed to help assist the service technician in locating and finding defective or worn parts in automobiles, heavy machinery or industrial equipment where vibration, rattles, squeaks and grinding sounds would be associated making the task very difficult or impossible to diagnose. When used with our specially designed hardware kits your smartphone will be transformed into a state of the art Sound & Vibration Detection Technicians Tool, allowing for ease of locating and finding those troubled areas. NOTE: Additional hardware is required to use this app. For information on how to purchase hardware please contact your local Mac Tools Distributor or call 1-800-MAC-TOOLS Features: User friendly interface and intuitive operation. Sound level reading displays average, peak and real-time values. Sound level readings are displayed in either Analog or Digital. Analog and Digital readings have 2 display panels the user can choose from. Analog Meter or Analog Wave-Form. Digital Numeric or Digital Bar Graph. Background sound off-setting, sample rates, decibel off-setting can be manually be set. Reset/Refresh buttons reset/refresh values to default settings. Sound Level Reading Sampling Rate Decibel Off-set Master Volume Control User information guide includes informative facts about sound perception and permissible noise level exposure as well as a sound level comparison reference chart. Additional Information: Required: Any iOS device running iOS5.0+. Recommended: iPhone 4 and newer/ iPod Touch 4 and newer. Compatible: iPad 2 and newer.

Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you. Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks. Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis. Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude. Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world. Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. This app allows you monitor and share the results of your measurements with other users. Measure and monitor all vibration and shocks using smartphone or tablet!
