FAQ
What is SoundMeter 2D used for?
SoundMeter 2D is used for probabilistic sound field estimation and mapping. It helps acousticians and engineers visualize sound pressure levels and their uncertainty in a given space, aiding in site surveys and diagnostic work.
Does SoundMeter 2D provide certified acoustic measurements?
No, SoundMeter 2D produces indicative measurements and is not a certified instrument under IEC 61672-1 or equivalent standards. It is intended for exploratory work, not regulatory or legal applications.
What kind of microphone accuracy can I expect with SoundMeter 2D?
The accuracy of SoundMeter 2D results depends directly on the microphone used. The built-in iPhone microphone provides relative data, but an external Class 2 microphone is strongly recommended for improved accuracy.
What are the subscription options for SoundMeter 2D?
SoundMeter 2D offers weekly ($2.99), monthly ($5.99), and annual ($59.99) subscription plans for access to its full features.
How does SoundMeter 2D handle data analysis?
The app analyzes sound fields in third-octave bands from 25 Hz to 16 kHz, providing both estimated SPL maps and 95% confidence interval maps to show the reliability of the estimates.
Can I export my sound field data from SoundMeter 2D?
Yes, SoundMeter 2D offers structured PDF export, allowing you to include maps and summaries of your acoustic analysis directly in technical reports.
Is SoundMeter 2D suitable for educational purposes?
Yes, SoundMeter 2D is designed for researchers and educators teaching spatial acoustics, statistical field estimation, or acoustic measurement methodology, providing a practical tool for demonstration and learning.
How frequently is SoundMeter 2D updated?
The latest version of SoundMeter 2D is 3.01, which was last updated on March 19, 2026. This indicates a relatively recent update cycle for the application.
