Why does a number jump too quickly on SoundMeter+?

This problem is most likely because your finger accidentally touches or covers the microphone grill while measuring on an Apple device.

If using iPhone:

When facing, its microphone is located at bottom left (i.e. the left grill on bottom).

If using iPad:

When facing, its microphone is located at top center (i.e. a small grill centered on top).

If using iTouch:

When facing, its microphone is a small grill located at top right on the back. It is adjacent to camera jack.

Solution:

Please make sure your finger does not touch or cover the microphone grill.
