Comparative Analysis of HRTFs Measurement Using In-Ear Microphones.

The head-related transfer functions (HRTFs) describe the acoustic path transfer functions between sound sources in the free-field and the listener's ear canal. They enable the evaluation of the sound perception of a human being and the creation of immersive virtual acoustic environments that can be reproduced over headphones or loudspeakers. HRTFs are strongly individual and they can be measured by in-ear microphones worn by real subjects.

HRTFs Measurement Based on Periodic Sequences Robust towards Nonlinearities in Automotive Audio.

The head related transfer functions (HRTFs) represent the acoustic path transfer functions between sound sources in 3D space and the listener's ear. They are used to create immersive audio scenarios or to subjectively evaluate sound systems according to a human-centric point of view. Cars are nowadays the most popular audio listening environment and the use of HRTFs in automotive audio has recently attracted the attention of researchers.

On the Importance of the Sound Emitted by Honey Bee Hives.

Recent years have seen a worsening in the decline of honey bees ( L.) colonies. This phenomenon has sparked a great amount of attention regarding the need for intense bee hive monitoring, in order to identify possible causes, and design corresponding countermeasures.

A Smart Sensor-Based Measurement System for Advanced Bee Hive Monitoring.

The widespread decline of honey bee ( L.) colonies registered in recent years has raised great attention to the need of gathering deeper knowledge about this phenomenon, by observing the colonies' activity to identify possible causes, and design corresponding countermeasures. In fact, honey bees have well-known positive effects on both the environment and human life, and their preservation becomes critical not only for ecological reasons, but also for the social and economic development of rural communities.
