Shock resistant is a common mark stamped on the back of wrist watches to indicate how well a watch copes with shocks.

The International Organization for Standardization issued a standard for shock resistant watches, which many countries have adopted. ISO 1413 Horology—Shock-resistant watches specifies the minimum requirements and describes the corresponding method of test. It is intended to allow homologation tests rather than the individual control of all watches of a production batch. It is based on the simulation of the shock received by a watch on falling accidentally from a height of 1 m on to a horizontal hardwood surface.

In practice shock resistance is generally tested by applying two shocks (one on the 9 o'clock side, and one to the crystal and perpendicular to the face). The shock is usually delivered by a hard plastic hammer mounted as a pendulum, so as to deliver a measured amount of energy, specifically, a 3 kg hammer with an impact velocity of 4.43 m/s. The watch must keep its accuracy to +/- 60 seconds/day as measured before the test.

Alva Noto is a stage name of sound artist Carsten Nicolai who uses art and music as complementary tools to create microscopic views of creative processes.^{[clarification needed]} Another alias he uses is Noto. He is a member of the music groups Signal (with Frank Bretschneider and Olaf Bender aka Byetone) and Cyclo. (with Ryoji Ikeda).

Nicolai was born in Karl-Marx-Stadt, East Germany. His interest in sound and its physical qualities may be inspired by his childhood obsession with bats, whom as a child he believed he could communicate with. He first studied architecture and landscape design before pursuing an interest in the theoretical properties of sound and space. Resettling in Berlin in the early 1990s, Nicolai founded the experimental music label Noton as a platform for his conceptual and experimental musical concerns. In 1996 this was to become Raster-Noton. Archiv Für Ton Und Nichtton with the collaboration of Olaf Bender.

Nicolai transforms sound by looping oscillators and tone generators. He does not use sequencers, but edits his work to give his compositions rhythmic structures. Clicks and glitches are not used as ornamental additions to the compositions but make up the essential rhythmic and harmonic elements of the work. He frequently samples electronic information transmission sounds such as fax tones, modem sounds and telephone pops and clicks are sampled and organised.^{[citation needed]}, among other overlooked sound sources.
