Measured: iPhone 16 Pro microphone frequency response and directivity

Leave a comment

Frequency Response In order to measure the frequency response of the iPhone 16 Pro’s microphone, a lab-grade reference microphone (PCB model 378B02 1/2-inch pre-polarized free-field condenser microphone) was positioned facing the iPhone mic approximately 1mm away from the phone within our anechoic chamber. The speaker was behind the PCB mic, facing the iPhone. Both microphone signals were fed into a 485B39 USB stereo ICP signal conditioner and the response of the iPhone relative to the reference mic was measured using SignalScope’s Dual FFT Analyzer. Then, the iPhone and PCB mic were rotated 180 degrees, keeping the same orientation and position relative to each other, and the response was measured again. The 2 resulting frequency response measurements were averaged. Each averaged […]

In the early days of the iPhone app store, I posted frequency response measurements of some iPhone microphones, including before and after certain iOS updates. This post represents the beginning of a new effort to measure the performance characteristics of iPhone microphones. Similar to the recent post on the Vision Pro microphone, two important metrics will be frequency response (magnitude) as well as the directional response of the primary (bottom) iPhone microphone. Frequency Response In order to measure the frequency response of the iPhone’s microphone, a lab-grade reference microphone (PCB model 378B02 1/2-inch pre-polarized free-field condenser microphone) was positioned facing the iPhone mic approximately 1 mm away from it. The speaker was behind the PCB mic, facing the iPhone. Both […]

SoundMeter 12.5 includes updated app for Apple Watch

Leave a comment

With the release of SoundMeter X and SoundMeter Pro 2022, version 12.5, SoundMeter’s companion app for Apple Watch has been completely re-written for better performance and improved support for newer versions of watchOS. In addition to sporting modernized software code, the SoundMeter watch app includes an interface for the Max Levels tool and adds max and peak levels to the sound level meter display. It should be noted that the SoundMeter watch app serves as a remote control for the corresponding app running on the iPhone–it doesn’t analyze or process any signals coming directly from the watch’s built-in microphone. On iPhone and iPad, SoundMeter 12.5 offers improved handling of data and audio files. On newer versions of iOS, external files […]
