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 […]

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. […]
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 […]

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 […]
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 […]
