In early December, Apple broke new ground by inviting CNET editor Patrick Holland to its secret labs where the iPhone’s video and audio capabilities were tested. Of particular interest were tests of the iPhone 16 in an anechoic chamber (an anechoic chamber). The cabin offers an environment where the entire surface is covered with special materials that prevent sound echo. Details in our news…

Apple tests iPhone models in this secret insulated room

First of all, these special areas are designed to examine the iPhone’s performance down to the finest detail. The aim of the tests in the anechoic chamber is to measure the performance of the device’s microphones under ideal conditions and to detect even the slightest errors. Since this special environment is a space where external sounds are reduced to zero, the frequency response, sensitivity and directional characteristics of the microphones are clearly evaluated.

Apple engineers say the iPhone’s microphones are exceptionally engineered. Despite having only four small microphones, the device performs close to professional audio recorders thanks to Audio Mix. In the tests we’ve seen, the iPhone 16 Pro is placed on a tripod and 24 speakers are positioned around the device like a snow globe, playing sounds of different frequencies.

As the microphones record these sounds, engineers analyze the data to evaluate the performance of each microphone. Patrick Holland’s next stop was a theater-sized lab where Apple tests video performance. This huge space is also used to optimize the performance of iPhone displays in different lighting conditions.

The lab’s large screen allows iPhone’s display settings, such as color, contrast and brightness, to be compared against ideal standards. The display can simulate different scenarios, from as dark as a movie theater to bright sunlight outdoors. This ensures that iPhone displays provide the best visual experience in all lighting conditions.

Apple engineers say that the iPhone is used in countless scenarios by different users all over the world, and that they strive to ensure that the devices are perfect in every environment. What do you think about this? You can write your opinions in the comments section below…
