New research shows that a lower reverberation time helps children cope with multi-talker listening situations

How children make sense of the complex signals they hear in the classroom depends partly on their hearing and cognitive abilities. But newly published research shows more about the important part played by the acoustic environment in this process; specifically, the role of reverberation time.  The ability to make sense of what you are hearing […]

Embracing Aural Diversity in Education through Universal Design for Learning

Classrooms the world over are filled with children that have a range of hearing conditions: from tinnitus and hearing loss to glue ear and noise sensitivity (hyperacusis). Meanwhile, schools claim to be “inclusive” without accommodating this aural diversity in any way. How can they achieve real inclusivity and accessibility by applying some of the core […]

Noisier teaching methods pose serious challenges for classroom design

Teaching methods shape the classroom sound environment Teachers of today have the shared goal of maximizing student engagement whilst maintaining a controlled sound environment. This has resulted in decades of innovation in educational approaches, classroom design and acoustic standardization. When additionally considering the influence of advancements in technological tools which have further augmented the field […]

Combination of Absorbers and Diffusers – An Experimental Study in a Classroom

This study provides information on how different acoustic treatments can be used to obtain different room acoustic qualities, and can be used to improve and fine-tune the room acoustic parameters for better speech and listening conditions in classrooms. The background overview The most common acoustical treatment in ordinary classrooms is a suspended sound absorbing ceiling. […]

Heart rate is a medically recognised stressor – Noise reduction gives teachers a significant long-term benefit

This is not new, however it is a fundamental aspect to consider when designing optimal sustainable indoor environments. By measuring/recording the heart rate of teachers, an indicator of stress was apparent in lessons and also over a longer more sustained period. Here is a short insight overview on stress as stated by ASA (American Heart […]

The impact of noise in education – a research summary

This new research summary is now available and lifts out evidence from a variety of research studies around the world. These studies address a broad range of important aspects which need to be considered in learning environments. It is based on a recent extensive literature review by Professor Emerita Bridget Shield made for Ecophon. We […]

Language students in Slovakia now appreciate the importance of good acoustics

Improved language lessons at Bilingual Grammar School in Žilina Slovakia. Before the acoustic improvements, students had to cope with poor speech intelligibility and excessive reverberation during their language lessons. It was not only the students who complained about the poor acoustics, but also teachers were angry about the environment because they had to strain their […]

Is it really possible to predict the room acoustic values in a non-diffuse room?

We made acoustic measurements as part of a remodelling of our training area at our head offices during the different phases of the acoustic treatment in the refurbishment. This is outlined in a previous Acoustic Bulletin post which highlighted the need for wall absorbers to remove the flutter echos, thus reducing the reverberation time and […]

Designing out “Chinook” flutter echoes in speech communication rooms

In September, it was a pleasure to present a work in progress “Optimising the acoustic design for a multi-purpose room used for speech communication activities” at ICA 2019 in Aachen. One of our inhouse head office rooms recently remodelled to accommodate a mixture of training functions. The sound environment for a room designed for speech […]
