Detuner is a generic term for a jet engine test cell exhaust system muffler. Aircraft jet engine testing facilities typically require a means to vent and dampen the engine exhaust. The engine exhaust flow is "augmented" with a relatively large flow of cooling air induced by a Venturi effect into the exhaust silencing system, so the exhaust ...
Bass guitarist and youtuber Charles Berthoud also makes extensive use of detuners, generally on a LeFay D-Tuner (which as the name hints was designed with a detuner on each string). Adrian Legg is a popular guitarist making use of rapid tuning changes. He was prominent in the late 1980s. The idea may have originated from the double bass extenders.
A Eurofighter Typhoon in a hush house facility with an air-cooled exhaust detuner. A hush house is an enclosed, noise-suppressed facility used for testing aircraft systems, including propulsion, mechanics, electronics, pneumatics, and others. [1] Installed or uninstalled jet engines can be run under actual load conditions.

A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional ...
The alternating magnetic flux set up by the growler passes through the windings of the armature coil, generating an alternating voltage in the coil. A short in the coil creates a closed circuit that will act like the secondary coil of a transformer, with the growler acting like the primary coil.
The pulse tube refrigerator (PTR) or pulse tube cryocooler is a developing technology that emerged largely in the early 1980s with a series of other innovations in the broader field of thermoacoustics.
Tracker action in Jørlunde church.Organ by Frobenius (2009). Tracker action is a term used in reference to pipe organs and steam calliopes to indicate a mechanical linkage between keys or pedals pressed by the organist and the valve that allows air to flow into pipe(s) of the corresponding note. [1]
