wearable soundproof microphone for mouth muffles voice of people who talk loud in public

shiftall’s Mutalk muffles voices with soundproof ‘mouthpiece’

People who talk loudly in public places such as offices, buses, metros, and trains may bother some people, if not everyone, so the technology company Shiftall has devised a wearable solution. Dubbed ‘mutalk’, the VR-shaped soundproof Bluetooth microphone is worn over the mouth to muffle the voices of people who need to talk loudly in public (take business meetings in a coffee shop or a group video call in a library as examples).

The wearable soundproof Bluetooth microphone isolates the wearer’s voice by -20 decibels or more, which means that the voice can be reduced to a level where a person sitting next to the wearer would not be able to hear what is being said. Shiftall says that in the high-frequency range between 1,600 Hz and 2,000 Hz, such as shouting, mutalk can muffle the sound by about -30 decibels.

Adjustable headband for hands-free conversation

Shiftall’s wearable soundproof Bluetooth microphone works like a mouthpiece. The wearer needs to place it upright on their desk to mute the microphone, and if they need to start raising their voice or yell, they just place it over their mouth, and the device will automatically muffle their voice. Since it is Bluetooth-ready, the handy and VR-shaped mutalk can be connected to smartphones too.

The device comes with an adjustable headband so the wearer can secure it to their head, allowing for hands-free conversation. The wearable soundproof Bluetooth microphone also comes with a 3.5mm stereo jack so earphones can be connected to it. In this case, the mutalk doubles as a headset since it can hear the incoming voice or sound. Shiftall says this can be useful when separate microphone and earphone devices cannot be configured.

The removable headband of mutalk makes it ideal for hands-free playing, VR, and other applications. By using the band, the wearer can use the controller to play games, take calls while typing, or jot down notes on a PC. The wearer may use the wearable soundproof Bluetooth microphone frequently, so Shiftall makes the mouth pad and the moisture-absorbing cushion removable so they can be washed in water.

mutalk may suit gamers who have the awareness not to bother their roommates or neighbors at night when they get carried away with the game. It may also fit those who have the dire need to take conference calls in a quiet office or open space, such as a coffee shop. With the wearable soundproof Bluetooth microphone, Shiftall gifts a harmonious life for those who do not want to be bothered by anyone’s noisy business.
