Packaging and transportation test
To simulate the most realistic transportation scenarios: the jolts during transportation, the collisions during express delivery sorting... We fixed the hearing AIDS on the test platform simulating a train carriage. After continuous vibration for 4 hours, the device's functions and acoustic parameters were completely free of deviation, and there were no signs of loosening on the appearance. Only then could it pass this test and ensure that the product remained intact during long-distance transportation.
Acoustic index testing
More than 30 acoustic indicators and parameters, including saturation sound pressure level, full-scale sound gain, equivalent input noise level, frequency response range, and total harmonic distortion, have been repeatedly tested twice to ensure that all indicators meet the standards. These parameters are important technical indicators for measuring the performance of hearing AIDS. For users, this means that every word they hear after wearing a hearing aid has passed through multiple layers of screening.
Drop test
In daily use, hearing AIDS are bound to accidentally fall to the ground. To address this issue, we have designed a strict drop test. During the test, we repeatedly dropped the hearing aid from a height of 1.7 meters onto the marble floor to realistically simulate the scene of the hearing aid accidentally falling in daily life. After 12 drops are completed, engineers will immediately check the performance of the equipment to ensure that there is no performance deviation after the drops.
Key press test
The buttons of a hearing aid are the parts that are operated most frequently in daily use. If the buttons malfunction after long-term use, it will greatly affect the user experience. If a user uses a hearing aid for 12 hours a day, with an average of 2 presses per hour, they will press the button approximately 50,000 times over a period of 5 years. To ensure that the hearing aid will not break down for five years, we conducted 50,000 press tests to make sure that the hearing aid works properly every time the user presses the button.
Waterproof test
Splashing water while washing hands, getting caught in the rain on rainy days, or accidentally dropping a hearing aid into water or a washing machine... And none of these will affect the normal use of our hearing AIDS. The waterproof rating of Flysound hearing AIDS reaches the IP68 standard. During the waterproof test, we completely immersed the hearing aid in a transparent container with a water depth of 1 meter. After removing the hearing aid, we connected it to professional equipment to test its acoustic performance. There was no damage to the hearing aid at all.
Salt spray test
When users wear hearing AIDS in daily life, they always sweat constantly in the scorching summer. They also sweat during outdoor activities, and sweat may become an "invisible threat" to the device. Sweat contains salt. If it adheres to metal parts for a long time, it will gradually corrode the metal coating. To address this scenario, we will conduct a 48-hour salt spray test in a precision salt spray test chamber. Make sure that after the test, the performance of the hearing aid will not decline in any way and it can work normally in all kinds of harsh environments.
Extreme temperature test
From summer to winter, from the north to the south, the climate differences in different seasons and regions pose a great challenge to the stability of hearing AIDS. To ensure that hearing AIDS can operate normally under various extreme temperatures, we conduct high and low temperature tests to simulate the usage environments of the devices in different seasons and regions. Hearing AIDS can function properly even when the ambient temperature drops as low as -20℃ or as high as 60℃.
Needle puncture test
Hearing AIDS are compact in size. The battery serves as the core power source, and its safety is directly related to the personal safety of the user. To eliminate the risk of battery fire and explosion, we have conducted strict needle-puncture tests on hearing aid batteries to ensure that they will not catch fire or explode.
Just as the popular song "Medal" goes: "And the wounds I have suffered are my medal ~" Every hearing aid that leaves the factory smoothly comes with eight test "MEDALS". In the future, Flysound will continue to use rigorous testing to safeguard every user's clear listening experience. Follow Flysound, and we will always be here to protect your hearing!
