• You can now export and print noise reports complete with date and time details, a noise graph, and LAeq maximum and minimum values split by octave bands.
In addition, you can also choose to add location details to the noise report.

With the brand-new loud warning feature, you can set your Apple Watch to alert you when you are:
• Speaking too loud
• Raising your voice or shouting
• In an environment where there is too much noise
Use it to:
• Prevent raising your voice
