IsoCal vs AcousticCheck

IsoCal is a prediction tool for calculating the sound reduction index of single walls with no cavity and double walls with a cavity between the leafs. It is possible to design walls with multiple leafs and different cavity/boundary connections (rigid connections, steel studs, staggered studs, etc.), different porous sound absorption material in the cavity of a double wall and predict the sound reduction index given as a Rw value in decibels [dB]. IsoCal comes built in with a catalog of well known material and porous material to use for designing the wall for optimal sound reduction. The user can also insert own materials in order to expand own personal database. IsoCal also provides a calculator for the prediction of absorption coefficients of porous materials. A simple calculator that lets the user choose the porous material thickness, air gap behind the porous material and more.

With AcousticCheck, the reverberation time (RT60) can be measured simple, fast and with high accuracy - even by people without acoustic expertise. AcousticCheck includes the following features for a smooth measurement experience: - Reverberation time measurement by impulse or sweep method - Up to nine consecutive measurements per measurement run for the most accurate results possible - Simple tutorial and guided measurement instructions - Detailed result display: Reverberation time on average and in octaves⁺ (chart, table) - Save measurement results for individual rooms or whole projects⁺ - Save and Share the measurement results as a chart and table⁺ - In-depth support⁺ Additional features for advanced and expert users: - Customizable room size (particularly helpful for measurements in larger rooms)⁺ - Adjustable start delay for impulse measurements⁺ - Save and Share results in CSV format (full measurement results, average reverberation times, correlation coefficient rT20 & signal-to-noise ratio SNR included)⁺ - Information on the room and additional notes can be added to the result export - Photos can be added to the result export - Optional export of impulse responses as WAV files⁺ ⁺only included in AcousticCheck Plus This app does not collect, use, store or transfer personal data.
