Shock wave shock wave, creating a process of destructive interference. The sonic boom associated with the passage of a supersonic aircraft is a type of sound wave produced by constructive interference. Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance. When a shock wave passes through matter, energy is preserved but entropy increases. This change in the matter's properties manifests itself as a decrease in the energy which can be extracted as work, and as a drag force on supersonic objects; shock waves are strongly irreversible processes. Shock waves can
Twang Twang Shock-A-Boom Twang Twang Shock-A-Boom Twang Twang Shock-a-Boom is an acoustic three-piece band led by Davíd Garza. The name is derived from the sounds of the guitar, bass, and drums. Twang Twang Shock-a-Boom was described by the Austin Chronicle as “one of the most breathtaking musical projects Austin has ever seen.” . For 10 months, the trio of Davíd Garza, Jeff Haley, and Chris Searles played humorous tunes with the bare-bones setup of guitar, upright bass, and a guitar case standing in for drums. It began when Garza and his music-school friends decided to go busk in the West Mall of Austin,
