One of the many labs of the R&D centre housed several acoustic chambers. Pyramid-shaped foams were specially designed to absorb sound lined the entirety of the inner walls. These were used to ensure that the testing of the smartphones’ audio quality was isolated from external factors. Staying in these rooms for just mere minutes could only be described by two words – deafening silence.
A separate acoustic chamber was also used as a controlled environment, with speakers at every corner and side of the walls. These speakers were pointed at the head of a dummy with a Huawei smartphone placed at its ear, positioning it as if a phone call was being made. To simulate it further, audio can also be played through the mouth of the dummy as if a person was speaking.
A noisy environment can also be simulated through the surrounding speakers. This allows the engineers to ensure that the smartphone could both receive and transmit clear audio when making a call. The sound levels could also be tailored to prevent the phone from being too loud and possibly damage the user’s hearing.
Endurance & Durability
Durability is definitely one of the deciding factors for many when purchasing a smartphone. That is why there is a whole lab dedicated to test the endurance of various aspects of the devices. The lab consists of multiple testing contraptions that can be seen below.
