The Internet-of-Things lightbulb provides light and audio. This light bulb can actually transmit audio above 18kHz which means you really can't hear it. But a phone can.

Easy to install with no speaker wires, remote controls or power cords, no installation hassle, only your smart phone/device. Wirelessly connect Pulse Solo from any Bluetooth enabled device to enjoy light and sound in a whole new way.

Published specifications - LED lights: 6 watts, 550 lumens, 2700K (warm white), beam angle 105 degrees. Audio: 2 x 3 watts @ 8ohm, rated 260Hz - 18kHz.

The speakers play audio that consists of tones at specific frequencies above the normal range of human hearing. In this instance the letters A to Z are assigned frequencies from 18000Hz (18kHz) upwards with a step of 75 hertz, so that A = 18000, B = 18075, C = 18150 ... Z = 19875.

Using this ‘code’ of letters it is possible to transmit letters, words and sentences to any device with a typical microphone and some software to decode the message.

The non-descript looking black oblong is a "smart-phone". It's smart. It is a phone. It's also a sensor array, a computer and connects to the internet.

The new Galaxy S5 offers consumers a refined experience with innovation of essential features for day–to–day use. It combines an advanced camera, fast network connectivity, dedicated fitness tools and enhanced device protection features as consumers stay fit and connected in style.

Published specifications - Chipset: Qualcomm WCD9320, S1221 6592 primary SMB microphone. Jack: 24-bit/192kHz audio.

The main microphone on this smart phone is accessible via software so that an app developer may turn it on and record any sound that is present. In this case the software doing so listens for specific frequencies at specific amplitudes, referred to as near ultra-high audio.

If a start tone occurs (A = 18kHz) it then listens for any more that might mean it is hearing an intelligible message and not random noise.
