Measured: iPhone 17 Pro microphone frequency response and directivity

Hardware, iOS, iPhone, News

Frequency Response I measured the frequency response of the iPhone 17 Pro microphone by positioning a lab-grade reference microphone (PCB model 378B02) approximately 1mm away from the phone (facing the mic) in our anechoic chamber. The reference mic was connected directly to input 1 of a model 485B39 dual channel USB interface. The iPhone microphone signal was routed directly to a USB-C to 3.5mm headphone adapter using SignalScope’s audio play through function (with measurement mode enabled) and from there to input 2 of the 485B39. The response between the 2 microphones was measured with SignalScope’s Dual FFT Analyzer (on a Mac) with the microphones facing toward and away from a loudspeaker which was generating a swept sine excitation signal.

Measured: iPhone 15 Pro Max microphone frequency response and directivity

Hardware, iPhone, News

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 […]
