About me

Hello! I'm Sergio, and this is your chance to get to know me better. Science, particularly acoustics, is my passion, and I enjoy photography and videography as hobbies.

As an Audiology System Engineer at Oticon's Audiology and Software team, I am dedicated to developing innovative solutions and concepts for hearing devices. I have a background in Acoustic Engineering (UFSM-BR), a Master's degree in Mechanical Engineering (UFSC-BR), and a Ph.D. in Hearing Sciences (Nottingham-UK).

As an Early Stage Researcher at the Eriksholm Research Centre as part of my industrial Ph.D., I gained expertise in evaluating sound localization and focused on creating realistic communication scenarios. I also designed the Iceberg auralization method to create auditory stimuli for audiological experiments.

My ultimate goal is to continuously improve my skills and knowledge in my field to impact people's lives positively.

Research Interests

Bone Anchored

Bone-anchored hearing systems are surgically implanted prosthetic devices that treat hearing loss. The sound vibrations are captured, processed, and sent through the skin, bypassing the ear parts that aren't working.

Spatial Audio

Various spatial audio techniques, with different complexities, qualities and paradigms, allow virtualization of both individual sound sources and sound fields. Through the process called auralization, files can be created that can be reproduced and perceived as spatialized audio.

Immersive Technologies

Immersive technologies integrate virtual and real-world elements. Virtual reality is the most well-known technique. In virtual reality, users are immersed in a computer-generated experience. Augmented reality superimposes digital information in the real world. Augmented reality enhances the real world with images, text and other virtual information. In turn, mixed reality allows users to interact in real time with virtual objects, as if they were real objects, within the real world.

Spatial Hearing Research

Study of the spatial aspects of hearing impairment, the behavior of normal and disabled listeners and improvements that the devices can bring to mitigate related problems. In particular, the study of realistic communication scenarios through spatial audio reproduction systems. The aim is to create the necessary conditions to investigate benefit provided by hearing devices, for example, reducing daily auditory effort.

Science Communication

In a world that is increasingly globalized, connected and with more readily accessible technologies, a considerable portion of the population still has no interest in science, technology and the functioning of their devices and programs. This may be in part because people do not understand communication provided by the academic-scientific world. Scientific communication is the practice of informing, educating, sharing wonders and raising awareness about topics related to science. Among so many genres on YouTube, scientific communication presents new ways to connect with a larger audience and in less orthodox ways. The world has evolved thanks to science and scientific communication is changing.

Room Acoustics

Room Acoustics is the study of physical acoustics that aims to model and describe the propagation of sound energy in a closed or semi-closed space. Sound waves are affected due to the geometric composition and the physical properties of the materials. That creates an identity for each space, thus affecting the quality of a sound, be it speech, music or any type of noise.
