Measured: iPhone 15 Pro Max microphone frequency response and directivity
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 […]
