What is the connection between a volcano, DLR and UTP? When the Icelandic volcano Eyjafjallajökull erupted in 2010, the massive ash cloud traveled across Europe, also reaching the Rhine arena. There, residents under the prime flight paths found that, for the first time in a long while, they could open their windows during the Easter vacation peak travel time. With fewer aircraft, the noise dropped to a tolerable level. This incident provided a scenario that highlighted the stressful effects of aircraft noise, especially in areas with large airports that serve as transportation hubs for logistics and travel.

At GRAS, we love diving deep into the finer details of measurement microphones - and apparently, so do our followers! In fact, this was one of our top-performing LinkedIn posts of 2024: Did you know that the small holes on your microphone serves a vital role in acquiring data? Proper microphone venting can mean the difference between good actionable data, and data corrupted by pressure inequalities between the front and back of the microphone diaphragm. This application note explains how and why the vents work, and why some microphones are front vented and others rear vented.

It was a testament to the profound impact Mr. Rasmussen had on the sound and vibration industry - and on everyone who met him. His innovative spirit and dedication to excellence remain the foundation of GRAS, and we are proud to carry his legacy forward. For those who wish to learn more about his extraordinary life and achievements, we invite you to read the blog post we shared in his honor: https://lnkd.in/ddKKZFKK >

Measuring the Sound Pollution impact of Santa’s Sleigh on Your Neighbourhood With Christmas Eve fast approaching, Santa’s sleigh will soon be dashing across rooftops at high velocity. This once-a-year event brings a unique challenge: measuring the sound impact of sleigh landings in populated areas. Between aeroacoustic noise from sleigh speeds and the added intensity at low altitudes, due to the density of the air, it’s a public health issue no one’s talking about – but one that must be addressed. The GRAS 41AC-3 CCP Outdoor Microphone for Community & Airport Noise monitoring is uniquely suited for documenting the effects of Santa’s multiple landings. With state-of-the-art weather protection and extensive use of high-grade stainless steel, the 41AC-3 is ideal for long-term unattended monitoring of community noise and noise from overhead sleighs. In addition, it is equipped with GRAS-patented SysCheck2 technology for verifying measurement chain integrity – so you can stay focused on Christmas preparations without worrying about your sound measurement setup.
