If you hear a “clack” sound for every key press: Conventional keyboards use membrane or scissor key switches with rubber domes that have an uncertain and spongy feel, greatly vary their sensitivity through their short life, and require too much force for every key press. The Infrared Mechanical switches used for each key in the Truly Ergonomic keyboards require very low force to activate and provide gentle tactile feedback when pressed that helps you feel when each key registers. If you hear a loud sound for each keypress while using your Truly Ergonomic keyboard, it means you are using too much force – likely badly influenced by conventional products. You should not hear a loud sound when pressing the keys. We suggest you press the keys as lightly as possible, just enough to activate the key press. It is highly recommended to type while floating your hands, like playing the piano, and only rest your palms on the palmrest when not typing. Resting the elbows on the chair armrests or forearms on the desk is ok. If you are accustomed to typing with keyboards using rubber domes – the most common type for most keyboards as are the cheapest, or using scissor switches like those found in laptops and portable computers, you might be inadequately accustomed to “hammer” the keycaps. In cheap keyboards, you need to hammer the keys for these to work. This means that you are accustomed to using excessive force to press the keys, for these to go all the way down and detect the keypress, as rubber domes require you to press them with excessive pressure for these to work. But, Truly Ergonomic keyboards are manufactured with optical-mechanical switches, where you do not need to hammer the keys. A gentle press is all you need to press the keys past the middle where the actuation takes place. This means that you only need to reach about halfway for the keypress to send the signal to the computer. We suggest you type using minimal force, the least force you can use to press the keys as long as the keys send the letters/symbols to the computer. Once you get accustomed to using optical mechanical switches by applying the least force required to actuate the keys, and for the keyboard to send the characters to the computer, the keycaps will make much less sound compared to hammering the keys, and you will be able to work even more comfortably.   If you hear a “resonant metallic” sound for every key press: Mechanical keyboards, like the Truly Ergonomic keyboards, have a mechanical switch under each key. The mechanical switch contains a metal spring that, in some instances, when pressed and released quickly, causes the spring to resonate and produce a “metallic ping” sound. The Truly Ergonomic keyboard has an EVA foam in between the metallic Top-body and the PCB (where all the electronic components reside) to reduce this metallic sound, but some individuals under some circumstances can still hear this particular metallic sound. You can acquire a ‘wide desk/mouse pad’ that could help allow the keyboard to become stable; like: https://www.lttstore.com/products/deskpad. The entire keyboard will be over a cushioned surface that will help reduce the ping sound.
