Acoustic microscopy acoustic microscope (CSAM), and C-mode scanning acoustic microscope (C-SAM). More recently acoustic microscopes based around picosecond ultrasonics systems have demonstrated acoustic imaging in cells using sub-optical wavelengths working with ultrasonic frequencies into the multi-GHz. Since the vast majority of acoustic microscopes in use today are C-SAM type instruments, this discussion will be limited to these instruments. Ultrasound is broadly defined as any sound having a frequency above 20 kHz, which is approximately the highest frequency that can be detected by the human ear. However, the acoustic microscopes emit ultrasound ranging from 5 MHz to beyond 400 MHz so that micrometre
Lost Frequencies Lost Frequencies Felix De Laet (born 30 November 1993), known by his stage name Lost Frequencies, is a Belgian DJ and record producer. He is best known for his singles "Are You with Me" in 2014 and "Reality" in 2015. The name "Lost Frequencies" was first used when De Laet had used old songs, which he calls 'lost frequencies' to make remixes when he started the project. In 2014, Lost Frequencies made a remix of country artist Easton Corbin's "Are You with Me". The song had originally appeared in Corbin's second studio album, "All Over the Road", but had not
