Sound Technology
An important element that distinguish Dexibel
Edphones with the rest of the headphones is it
Hearing Protection
Children's hearing are very sensitive and can be fragile. Continuous exposure to loud volume will cause irreparable damage. This is why all Edphones from the Tender™ series comes equipped with Hearing Protection capping at 85dB, 94dB and 105dB.
​
Limiting the speaker volume to 85dB or 94dB can prevent hearing damage; however, students sometimes require the option to increase volume to normal, higher levels like 105dB. Some Tender Edphones allow this setting via a key can is given to the parents or caretaker.
ANC Transparency
When referring to ANC, Edphone's speakers comes with an extra microphone to pick up surrounding sound. Using AI algorithm it allows (1) canceling all noises or (2) amplifying surroundings as transparency mode.
​
Active Noise Cancelling for hearing is important for students to focus on their work by blocking out surrounding sounds or distractions. Yet, in some cases, they are required to be even more alert of the environment. Transparency mode provides amplification of surrounding sound mixed with the original sound source, often giving the sensation of not wearing a headphone. Contrasting with the feeling of air-pressure when using Active Noise Cancellation, transparency mode allows user to wear it all day.
ENC Microphone
ENC stands for Environmental Noise Cancelling. It is also a form of Active Noise Cancelling, but referring to the microphone instead of the speakers as described above. By removing the background noise picked up from the microphone, user can be clearly heard in the noisiest environments without the need to shout. ENC uses two microphones, one for picking up user's voice, one for picking up surrounding noise.
​
Using an advance AI Alogrithm, the MCU compares the sound picked up by both microphones and removing only the noise sent to the receiving end. Dexibel includes ENC for both student and teacher products to address possible noisy environment at school.
