Task-irrelevant speech is among the most common and disruptive sources of noise in modern office environments. For acousticians, the challenge has long been: how do we objectively assess the distraction caused by such fluctuating, speech-dominated environments using tools readily available in the field? A new study by Hongisto et al. (2025) offers a solution. It […]

How noise affects decision-making
Noise has always been seen as a challenge in workplaces, but its impact on decision-making—especially in experience-based judgments—is not yet fully understood. This article looks at two research studies that explore how noise affects decision-making and the practical implications of their findings. Why room acoustics matter in decision making Efficient decision-making is essential in workplace […]

A new BBC Sounds “Start the Week” podcast with sound guru Prof. Trevor Cox, Fiona Smyth author and musician Jess Gillam combine to give a great overview of the history and development of architectural acoustics… Some fascinating acoustic discussions and insights: Echo vs reverberation, distinct echo vs reverberant bloom… Listen […]
New Aural Diversity toolkit helping designers create more inclusive spaces
Aural Diversity Toolkit Arup and the Aural Diversity Network have developed a toolkit to help designers create spaces and environments that meet the needs of everyone. This toolkit addresses the broader needs of those with aural sensitivities and provides a comprehensive set of recommendations, further research and other relevant aspects to consider to better inform […]
Active noise-cancelling headphones do not improve cognitive performance in office noise environment
In modern open-plan offices, noise from conversations and background activities can significantly impact employees’ productivity and well-being. Active noise-cancelling (ANC) headphones are often employed as a personal solution to reduce distractions and control the acoustic environment. But how effective are these devices in enhancing performance, reducing stress, or improving the overall work experience? This article […]
Empirical Method for Predicting Speech Sound Propagation in Offices
ISO 3382-3 describes how to assess sound propagation and speech intelligibility in open-plan offices. At the recent Inter-Noise conference in Nantes, Rainer Machner presented Hongisto and Keränen’s (2013) regression-based model for predicting ISO 3382-3 parameters. By analyzing data from 10 office spaces, he evaluated the model’s performance and gave practical recommendations for its use in […]
Acoustics in Green Buildings
Acoustics in green buildings, by Hassan Al-Ramadani Over the last twenty years, there has been a remarkable surge in the construction industry’s adoption of green buildings. This has been due to public awareness of adopting sustainability and sustainable practices. Additionally, several studies have proposed that occupants of green buildings have a higher level of productivity […]
Irrelevant speech makes perceived workload higher
Irrelevant speech, or background conversations, has been shown to impair cognitive performance and cause physiological stress. Recently published research demonstrated that working during task-irrelevant speech not only increases stress, as measured by heart rate variability, and reduces accuracy but also increases annoyance and perceived workload. Method Thirty participants performed two cognitive tasks (n-back and serial […]
Three strategies towards greater sustainability – presentation at DAGA conference
The 50th Annual Congress of the German Acoustical Society (DAGA) was held in Hannover this year. Celebrating decades of innovation and scientific advancement, DAGA 2024 featured presentations dedicated to sustainable practices in acoustic research and technology. This article provides a summary of the presentation by Achim Klein from Ecophon Saint-Gobain on the efficiency, consistency, and […]
