As smart home technology evolves, it's getting smarter, easier and more convenient for the user. Now, much of the current talk is focused on voice command, but soon, will be directed at sounds, noises and vibrations, according to this piece from The Digital Journal.

The Internet of Things has taken a foothold in many homes. According to some technologists, the next stage for the smart home is the Internet of Sound, based on sensors detecting alterations with vibrations, sound and electrical field.

The idea behind the Internet of Sound concept is to use the collected sound, vibrational and electrical changes to improve energy consumption. A secondary area is an alert, in terms of monitor movements of people inside the home.

The smart home concept has accelerated in recent years, through innovations in home automation. Many of the applications have been tailored towards convenience (such as changing light intensity to suit mood) or entertainment, with voice activated music systems, as examples. Many types of ‘domotics’ involve the use of a central hub.

The concept comes from engineers based at Case Western Reserve University. The researchers have been examining a new range of smart-home sensors. Such devices could be designed to capture vibrations, sounds and small changes relating to ambient electrical field.

With the idea of using sound to deliver energy saving, a building of the future could be equipped with sensors that could adjust activity to suit the number of occupants. The appeal of such a concept is with data privacy. According to the research team, a self-adjusting building could operate with just a few small, hidden sensors located in the walls and floor, without the need for invasive or intrusive cameras.
