PURPOSE:To reduce noise at the outside of a vehicle by driving a speaker provided in a duct in a way of sending a sound wave to cancel the noise at the outside of the vehicle based on a signal from a sound wave sensor provided to the depth of the plural ducts formed by division of...
Noise controller and noise control method for reducing noise from outside of spaceA noise controller includes a first control unit that outputs a control signal for outputting sound for reducing noise to a first speaker, a first characteristic circuit that generates a signal by performing convolution...
The curtains are very heavy which is extremely good for blocking out noise. Coming in different colors as well as different sizes, these curtains make a promise that is true to their name in that they block out nearly 100% of all outside light. This makes these the ideal curtains to hang...
