Frequently Asked Questions

General & Product Overview

What is acoust IQ? 
acoust IQ is an app-based platform for professional, standards-compliant sound level measurements using an iPhone or iPad in combination with a digital Class 1 or Class 2 measurement microphone.

Who is acoust IQ designed for? 
acoust IQ is designed for engineering consultancies, manufacturers, suppliers, operators, research institutions and testing organisations in fields such as industry, mobility, environmental acoustics, construction, and research & development. & Entwicklung.

Hardware, Devices & Microphones

Which devices are supported? 
acoust IQ runs on iPhone models starting from iPhone 15 and on iPads with a USB-C connection. 

Which microphones can be used? 
The app supports digital Class 1 and Class 2 microphones. Our primary recommendation is professional measurement microphones from Microtech Gefell with an integrated digital preamplifier. 

Where can microphones be purchased? 
Microphones can be purchased directly via acoust IQ or from Microtech Gefell: www.microtechgefell.de 

Can other microphones be used?? 
Yes. Alternative microphones (e.g. UMIK) can generally be used. However, acoust IQ follows a whitelist policy to ensure reliable and reproducible measurement quality. Other microphones can be tested in our laboratory upon request. For professional applications, we continue to recommend Microtech Gefell. 

Which microphone class is recommended? 
Microphones of other classes are technically compatible. For high-quality, standards-compliant measurements, we strongly recommend using Class 1 microphones. 

Are measurements possible in very small or confined spaces? 
Yes. Measurements in very small spaces or narrow gaps are possible.

 Why doesn’t acoust IQ work with every microphone? 
To ensure acoust IQ delivers high-quality measurement results, the app must be technically matched to each specific microphone. This includes, among other things, microphone-specific parameters as well as calibration and device settings, so the microphone and the app work correctly together. That’s why acoust IQ supports only selected, validated microphones (whitelist). If you would like to use a specific microphone, we’ll be happy to review it. Please contact: Dr. Michael Mosch

Measurement Capabilities & Accuracy

Which acoustic parameters are supported? 
acoust IQ supports parameters such as LAeq, LAFmax, LCpeak, Ptime histories, narrowband spectra, and third-octave band analysis. 

Is acoust IQ suitable for standards-compliant measurements? 
Yes. When used with certified Class 1 or Class 2 microphones, acoust IQ is designed for professional, standards-compliant sound level measurements.

Is post-processing destructive? 
No. All editing is non-destructive. The original raw data remains intact at all times, and all recalculations are fully traceable.

Multichannel & Remote Measurement

Can multiple devices be used simultaneously? 
Yes. acoust IQ supports multi-device and multi-location setups and is suitable for distributed measurement campaigns. 

Does acoust IQ support remote measurements? 
Yes. Extended configurations enable remote monitoring and control of measurements via a web interface. 

How does remote measurement work with unstable internet connections? 
Live previews are transmitted efficiently, while raw data is uploaded asynchronously. This ensures reliable operation even with limited or unstable bandwidth.

Long-term Measurment

Is acoust IQ suitable for unattended long-term or continuous monitoring?? 
acoust IQ is primarily designed for flexible, mobile, and project-based measurements where the user is actively involved, offering an optimized and efficient workflow for these scenarios.

For specialized, unattended continuous monitoring (e.g., for plant or construction site monitoring), we recommend the expertise of our sister company within the Müller-BBM Group: Müller-BBM Industry Solutions GmbH.

Reporting, Data Management & Integration

How are reports created? 
Reports can be generated directly within the app using the integrated Report Generator. Measurement data and metadata are automatically combined into consistent documentation. 

Which metadata is captured? 
acoust IQ can capture GPS positions, timestamps, photos, notes and markers together with the measurement data. 

Where is my data stored? 
The entire backend infrastructure and data storage for acoust IQ is based in Europe. Your measurement data remains within the EU at all times – fully in line with GDPR and European data protection standards.

Licensing, Pricing & Procurement

Which product packages are available? 
acoust IQ is available in different configurations (Basic, Pro, Live/Remote), depending on required features such as cloud access, collaboration, or remote control. 

How much does the Basic package cost? 
The Basic package is available via the iOS App Store. Within the App Store, you can choose between monthly and annual billing options. Current pricing and payment details are available directly in the App Store.  

How is pricing handled for Pro and Live packages?
