A new invention has proven that audio can successfully be transmitted directly to a listener's ears without being audible to others around.

Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread out as they travel. This effect is particularly strong for low-frequency ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

According to a study published in Science, EPFL scientists have discovered how quantum interference and symmetry influence ...

Destructive interference of sound waves is the principle behind noise-cancelling headphones. Two waves are coherent when there is a meaningful relationship between their phases or when their ...

However, the residents of Delhi-NCR recounted the moment and said they also heard a loud sound. As Delhi-NCR was jolted by an early morning earthquake, National Centre for Seismology director ...

Hyundai’s speakers adjust their angle to minimise sound wave interference. Credit: Hyundai Mobis. Hyundai Mobis has developed a new movable sound system that is engineered to synchronise with ...

This reduces surrounding sound wave interference and offers high-quality sound. Designed to maximize the display size for enjoying video content when stopped or during autonomous driving ...
