Infineon Introduces First AEC-Q103 Qualified High-Performance XENSIV MEMS Microphone for Automotive Applications

Infineon Technologies AG announced the launch of the XENSIV IM67D130A MEMS microphone. The high acoustic overload point (AOP) of 130 dB SPL allows the IM67130A to capture distortion-free audio signals in loud environments, whether in- or outside a vehicle. The microphone also has an increased operating temperature range from -40°C to +105°C to enable various use cases in harsh automotive environments, enabling advanced driver assistance systems and predictive maintenance applications.

Ams Adaptive Noise Cancellation Technology Powers JBL Over-Ear Headphones

Announced earlier in January and scheduled to be available May 2021, the new JBL Tour ONE headphones will feature Harman's first adoption of Adaptive Leakage Compensation (ALC) technology from ams AG. ALC technology has already been deployed in various types of earbuds, including loose-fit earbuds, to provide consistently high noise attenuation as the earbud shifts position in the ear. Now Harman has deployed ams ALC technology in the JBL Tour One to provide the same consistency and high noise attenuation in over-ear headphones.

Practical Test & Measurement: Attenuators for Measurement

In this article for audioXpress, Jonathan Novick explains why the use of external attenuators are an effective and cost-effective way to measure signals above the maximum input voltage of an audio analyzer. Novick explains why there needs to be some consideration of the topologies and different attributes offered by such components for audio noise measurements. He compares the impact different attenuators’ thermal noise will have on measurements of distortion. This article was originally published in audioXpress, March 2019.

Bose Launches Noise-Masking Sleepbuds Following Indiegogo Campaign

Apparently, a large percentage of the population is looking for a solution to be able to get more hours of quality sleep without hearing city noise, neighbors or a snoring partner... So, you use earplugs, right? Well, not so fast. According to Bose, earplugs are not enough. You need an active system that fits in your ear comfortably when you are in bed and at least one of your ears is pressed against the pillow. That's why Bose designed the noise-masking, launched its very first campaign on Indiegogo (amassing an impressive $450,320 USD), and now made it available worldwide.

QuietOn Promotes Simple Active Noise Cancelling Earplugs

Reduce noise, sleep better and improve work ergonomics are benefits promoted by QuietOn, a new company based in Oulu, Finland, and one of the companies we have met at the CES 2017 Eureka Park, in Las Vegas. QuietOn earplugs are small and have no wires, combining active noise cancellation and acoustic noise attenuation to reduce low frequency "bass" noises, which are not addressed by normal earplugs.
