Infrasound is very low-frequency sound, below 20 Hertz (Hz), which humans typically can't hear. It can come from natural ...

Workplace hearing loss is one of the most common work-related illnesses. While hearing loss is preventable with earplugs, ...

Wireless sensors used in wearable smart devices and medical equipment must be capable of detecting minute changes while maintaining high operational stability. However, existing technologies often ...

The principle of this work is demonstrated by using a laser to levitated nanoparticles and make them carry an electric charge to become an antenna that receives an external electric field containing a ...

Researchers from Canada and France have created 'meta-earplugs' using Helmholtz resonators to reduce the booming voice effect and block low-frequency industrial noise. The design improves both comfort ...

Élodie Briefer grew up in the countryside near Geneva — and horses have long been a part of her world. "I was riding horses when I was young," she recalls. "I can't remember at which age I started, ...

Research conducted by a team of scientists from Kaunas universities, Lithuania, revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound’s effect on ...

Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...
