Voice Coil June 2023 features an extensive patent review in James Croft's Acoustic Patents column. The topic is a 2014 patent awarded to Nokia, offering an opportunity to revisit the history of electrostatic loudspeakers, with insights from Tim Mellow, one of the two listed inventors. In Test Bench, Vance Dickason focuses on the D8404-552000 Ellipticor cloth diaphragm dome midrange from Scan-Speak, and characterizes the SB Acoustics TW29BNWG beryllium dome and waveguide from the brand's prestigious Satori line.

HEAD acoustics succeeded in the standardization of the newly developed artificial ear with human-like ear canal (HEC). The new artificial ear is now standardized as Type 4.4 artificial ear in Recommendation ITU-T P.57. The HEAD acoustics HEC artificial ear not just fulfills the Type 4.4 artificial ear requirements, it is also the first ITU-T standardized artificial ear meeting the low-noise requirements for artificial ears as defined in the new chapter 7 of Recommendation P.57.

HEAD acoustics introduced a new and much improved design for its artificial heads paving the way for new era of communication and audio quality measurements. The new generation of artificial heads ensures a new level of realism, precision and flexibility when coupled with HEAD acoustics modular concept approach, meeting the most diverse of applications in the field of acoustic measurement technology.
