Microtech Gefell News – Sound Power Hemispheres for sound power measurements according to ISO 3744 and ISO 3745
NEW in the Microtech Gefell – program – Sound Power Hemispheres / SLH for sound power measurements according to ISO 3744 and ISO 3745 Internationally, manufacturers of all sound-emitting industrial and consumer goods devices are increasingly required by law to record and comply with the entire chain of human and environmentally relevant sound emissions. At the same time, consumer-oriented sound design is becoming increasingly important in product development, e.g. designing corporate and brand product sounds in the field of e-mobility in the automotive sector. The two sides of the same coin – Noise reduction and Sound creation The reduction of unwanted noise emissions from a vehicle is not only regulated…

Microtech Gefell and e-mobility – Noise reduction was yesterday – Product Sound Design will be the future
Noise reduction was yesterday – Product Sound design is claimed in future Microtech Gefell – New measurement tools & turnkey test benches for simulated indoor and exterior pass-by systems By Udo Wagner/Microtech Gefell/MTG E-mobility changes the world of acoustical engineering. The development of a new vehicle generation is going along with immense progresses in technologies of test bench systems and in the world of acoustic measurement. The e-mobility-world presents a host of new challenges for acousticians. In the century of e-vehicles noise emission is as low as never was possible in the time of combustion engines. But to low noise emission is dangerous, especially for pedestrians. Legislators in mostly countries…

Film history – Microphones made in Gefell and 75 years of DEFA
75 years of DEFA and microphones that made history On 17 May 1946, Deutsche Film-AG (DEFA) was founded in Potsdam-Babelsberg as a Soviet-German joint stock company. After the founding of the German Democratic Republic/GDR on 7 October 1949, the film studios, workshops and sound studios gradually passed into German hands. In 1953, the DEFA studios for feature films, children’s films, popular science films, newsreels and documentaries, film dubbing and the DEFA studio for animated films (1955) were established. The former Ufa studios, known for film classics of the 1920s such as Dr. Mabuse, The Gambler, Nosferatu – A Symphony of Horror, Fritz Lang’s Metropolis or The Blue Angel with Marlene…

Gefell`s M 990 a „heartbreaker“ – An up to date large-diaphragm condenser microphone in tube technology
Committed to the Georg Neumann heritage, Microtech Gefell/MTG stands for tradition and innovation since 1928. This is evidenced by the M7 PVC capsule, which has been handmade for more than 80 years. The renowned M7 capsule, created by Georg Neumann in 1932 and used in the original U47 and M49 microphones, is e.g. still found today in Microtech Gefell’s legendary UM 900 and several other models. In addition to the production of the classic M 7 capsule, MTG faced new challenges with the development of a completely new capsule generation. Following the principle of tradition and innovation, a completely new capsule was developed in the 1990s- the M 930 capsule,…
