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 […]

Assessing the indoor soundscape approach among university students’ home study places
After being inspired by Amneh’s research about students experience of their study soundscapes we caught up for an interview with her and found out more about Amneh and what her broader interests are around her research. Amneh has just recently completed her PhD with TU Delft. Do all university students prefer quiet and private study […]
The Impact of Noise on the Learning of Children and Adolescents
Recent research published by Universitat Rovira i Virgili [1] presents a meta-analysis reviewing the impact of noise on the academic and cognitive performance of non-university students. This meta-analysis compiles the most important and significant findings from numerous research studies conducted worldwide and confirms what much of the educational community and many parents had suspected: noise […]
Restaurants get louder—here’s how good acoustics and table spacing can break the cycle
In hospitality spaces such as restaurants, hotel lobbies, and cafés, escalating noise is more than just a nuisance—it’s a scientifically recognized phenomenon with measurable impacts on both guest experience and business outcomes. This is largely driven by the Lombard effect, a reflexive human response where people raise their voices in noisy environments to be heard. […]
New study to investigate students’ attitudes towards sound environments at their school
Researchers in sound environment design at KTH, will conduct a pilot study on students’ attitudes towards sound environments at Gantofta School Martin Ljungdahl, postdoctoral researcher and researcher in sound environment design at KTH, Institute of Technology in Stockholm, will conduct a pilot study on sound environments at Gantofta School in Helsingborg. To find out how […]
How Sound Shapes Our Schools: Teachers’ Perceptions of School Soundscapes
Guest post by Hatice Kurukose Cal, Phd candidate, Institute for Environmental Design and Engineering, UCL, UK Teachers play a key role in shaping the soundscape of a school, but how do they perceive the acoustics around them, and how does it impact their work? Our research delves into UK teachers’ perceptions of school soundscapes, exploring how […]
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 Child Perspective on Noise Exposure and Health Effects – Challenges and Strategies
The filmed keynote presentation from Inter-noise2024 this summer is now available. Abstract (plus some relevant slides from the presentation): The presentation discusses the challenges of adopting a child perspective on noise exposure and the health effects due to noise. It takes as a point of departure a child perspective on vulneralility, including exposure, susceptibility to […]
Autistic Students’ Sensitivity to Classroom Noise: Implications for Acoustic Design (and the) Impact of classroom noise on autistic students
This study is by Marco Caniato (Free University of Bozen-Bolzano and University of Applied Science HFT of Stuttgart), Federica Bettarello (University of Trieste), Arianna Marzi (Free University of Bozen-Bolzano) and Andrea Gasparella (Free University of Bozen-Bolzano) Inclusion of Additional Support Needs (ASN) sensitivities Students on the autism spectrum often experience heightened sensitivity to environmental sounds, which […]
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 […]
