Introduction: Surrounding spherical loudspeaker arrays facilitate the application of various spatial audio reproduction methods and can be used for a broad range of acoustic measurements and perceptual evaluations. Methods: Installed in an anechoic chamber, the design and implementation of such an array of 68 coaxial loudspeakers, sampling a spheri...
Article
Understanding speech in noisy environments, such as classrooms, is a challenge for children. When a spatial separation is introduced between the target and masker, as compared to when both are co-located, children demonstrate intelligibility improvement of the target speech. Such intelligibility improvement is known as spatial release from masking...
Thesis
Full-text available
Hearing loss (HL) has multifaceted negative consequences for individuals of all age groups. Despite individual fitting based on clinical assessment, consequent usage of hearing aids (HAs) as a remedy is often discouraged due to unsatisfactory HA performance. Consequently, the methodological complexity in the development of HA algorithms has been in...

Purpose Working memory capacity and language ability modulate speech reception; however, the respective roles of peripheral and cognitive processing are unclear. The contribution of individual differences in these abilities to utilization of spatial cues when separating speech from informational and energetic masking backgrounds in children has not...
Article
Virtual acoustic environments have demonstrated their versatility for conducting studies in various research areas as they allow easy manipulations of experimental test conditions or simulated acoustic scenes, while providing expansion possibilities to related interdisciplinary and multimodal fields. Although the evolution of auditory and cognitive...
Preprint
Full-text available
Research in the last decades has pointed out negative effects of noise on cognitive processing and general health. Depending on the frequency and level of exposure as well as individual shielding potential, risk groups like children or elderly people may be particularly vulnerable to commonly known consequences including a reduced attention span, i...
Article
Full-text available
The acoustic qualities of a room can have a deleterious effect on the quality of speech signals. The acoustic measurement of reverberation time (RT) has shown to impact second language (L2) speech comprehension positively when lower due to release from spectral and temporal masking effects as well as top-down processing factors. This auralization e...
Conference Paper
Significant advances in the field of Virtual Acoustics facilitate the simulation of controlled acoustic scenarios to be subsequently used for the reproduction of plausible or even authentic sound fields. Such controlled scenarios introduce interesting possibilities for the design and conduction of auditory experiments as they aim at representing re...
Article
The ability to perform spatial release from masking (SRM), i.e., benefiting from a spatial separation between target and distracting talkers, is an important developmental skill for children to navigate noisy environments such as classrooms. While studies on children’s SRM were mostly conducted in anechoic rooms or sound booths to date, little is y...
Article
Full-text available
This study considers whether bilingual children listening in a second language are among those on which higher processing and cognitive demands are placed when noise is present. Forty‐four Swedish sequential bilingual 15 year‐olds were given memory span and vocabulary assessments in their first and second language (Swedish and English). First and s...
Article
Full-text available
Telephone conversation is ubiquitous within the office setting. Overhearing a telephone conversation—whereby only one of the two speakers is heard—is subjectively more annoying and objectively more distracting than overhearing a full conversation. The present study sought to determine whether this "halfalogue" effect is attributable to unexpected o...
Conference Paper
Former studies provided different reasons for noise in schools and preschools. As such, room acoustic design and internal and external background noise sources are contributing to the overall noise level, in addition to the considerable proportion of noise which is generated by the children themselves. Current noise ratings mostly rely on single va...
Article
A recently developed binaural real-time reproduction system has been extended with an interface to research hearing aids allowing for the conduction of auditory research on subjects with hearing loss. Simulated hearing aid signals based on measurements of generic hearing aid-related transfer functions are additionally processed on a master hearing...

Full-text available
Classrooms with demanding acoustic requirements for children fitted with hearing aids can be simulated effectively by real-time virtual acoustic environments. Physical accuracy is achieved using room impulse responses and a binaural reproduction system extended by research hearing aids. The generation of virtual sound sources is based on individual...
Article
To study speech perception of children with hearing loss in virtual acoustic environments (VAE), a pair of research hearing aids has been previously integrated in a real-time dynamic binaural reproduction system. The auralization included simulations of room acoustics using individualized head-related and hearing aid-related transfer functions (HRT...
Conference Paper
Full-text available
The speech reception threshold (SRT) is measured to assess speech recognition under the presence of distracting noises. However, most laboratory test conditions do not reflect the complexities of real-world listening, such as listening with moving noise sources. In this study, a standard digit-triplet test for measuring SRT at 50% intelligibility i...
Conference Paper
To evaluate the performance of hearing aids in difficult everyday situations, more realistic listening test conditions need to be developed in cooperation with hearing aid users. To simulate such realistic test conditions, virtual acoustic environments (VAE) provide the flexibility of reproducing real-world scenarios and enable stable listening tes...
Conference Paper
Full-text available
Sound localization performance in binaural reproduction systems using acoustic crosstalk cancellation filters and loudspeakers relies on head-related transfer functions and has been previously examined in several studies on normal-hearing listeners. For applications on listeners fitted with bilateral hearing aids, the binaural playback setup has to...
Conference Paper
Full-text available
Improved efficacy of auditory training was demonstrated in studies by Cameron and Dillon (2007-2012) on normal hearing children with spatial processing disorder, also common among those with hearing loss, by presenting speech training materials in virtual acoustic environments (VAE) with head-related transfer functions (HRTFs) measured from an adul...
Conference Paper
The most important requirements that should be covered by state-of-the art hearing aid algorithms include robustness and flexibility in challenging real-life situations. However, there is still a big gap between the validated performance of such algorithms tested under laboratory situations and the perceived performance of the end-user. To overcome...
Conference Paper
State-of-the-art acoustic virtual reality systems offer various methods to spatialize sound and create complex environments. In listening setups with limited space methods which require a low number of loudspeakers and little hardware to synthesize a surrounding sound field are preferred over those with higher hardware requirements. Such methods in...

This article discusses modal beamforming applied to a new microphone array prototype for panoramic audio recordings. Modal beamforming using conventional spherical microphone arrays is usually based on the decomposition of the sound pressure into spherical harmonics. To keep the error of the decomposition into spherical harmonics small a distributi...
Thesis
Full-text available
Alternatively to AB, XY or equivalence-stereophony-based surround recordings, spherical arrays have been investigated thoroughly in recent years as they permit recordings with high-resolution imaging of spatial sound. Nevertheless, this type of surround sound imaging is still a challenging research area. The particular challenge is that we have to...

Immersive audio is our everyday experience of being able to hear and interact with sounds around us. Simulating spatially located sounds in virtual or augmented reality (VR/AR) must be done in a unique way for each individual. This has been the object of extensive research in the past years; nevertheless, several major challenges are still to be tackled in this area, which require an improved understanding and modelling of the human spatial hearing mechanisms. Furthermore, the impact of immersive audio beyond perceptual metrics such as presence and localisation is still an unexplored area of research, specifically when related with social interaction within virtual environments, entering the behavioural and cognitive realms. SONICOM puts together some of the most important research centres across Europe to tackle these research challenges using a multidisciplinary approach. Research involves a mixture of digital signal processing and artificial intelligence, together with psychology and perceptual modelling, exploring new forms, levels and dimensions of interaction within auditory-based immersive environments. Furthermore, in order to reinforce the idea of reproducible research and promoting future development and innovation in the area of auditory-based social interaction, the SONICOM Ecosystem will be created and shared with the wider community, which will include auditory data closely linked with model implementations and immersive audio rendering components. --- The SONICOM project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement no.101017743.
Project
The purpose of this research project is to study if and how learning in second language is affected by class room acoustics and common background noise in school environment. Since the interaction between language (native and second) and acoustics has been reviled, this issue has to be investigated in detail, in order to have a school system that is inclusive for all students. The Swedish National Agency for Education states that “All pupils have the right to an equivalent education”. The interaction between acoustical factors and hearing status, children vs adults is well explored and reported by researchers, however, since population of immigrants is growing the need of research in education in second language is of high importance for our society.
