Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

On Thursday 24 November 2016 Moses George will defend his PhD dissertation ‘Legal Implications of Airport Privatization in India’. The defence will commence at 11.15 hrs, in the Academy Building of Leiden University. The Supervisors are Professor Pablo Mendes De Leon and Professor Brian F. Havel (DePaul…

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

Do natural soundscapes affect migratory decisions of fishes moving up and down rivers and is this process disturbed by vessel sounds?

This thesis addresses questions on effectively using variational quantum circuits for machine learning tasks.

Electric noise can be useful for scientists but inconvenient for chip manufacturers. They do share a wish to predict the amount of noise. PhD student Sumit Tewari overturns a century-old law relating noise to current. He defends his thesis on March 27th.

Two PhD defences on 9 June by behavioural biologist Errol Neo and underwater acousticianan Özkan Sertlek relate to measuring noise in the North Sea and the harm this noise can do to aquatic animals and their surroundings. Little is known about how harmful human noise can be to aquatic animals.

Birds around airports are more aggressive and sing as if they have hearing loss. Collaboration between researchers of Manchester Metropolitan University and the Institute of Biology Leiden has led to surprising new findings about the impact of anthropogenic noise on birds around airports. Publication…

Hans Slabbekoorn, researcher at the Institute of Biology Leiden, is one of the editors of the latest volume of the Springer Handbook of Auditory Research (SHAR). This book is filled with everything known about the effects of sound on vertebrates. Slabbekoorn’s contribution to the book as a co-author…

Are there acoustic cues for settlement stage larvae in deep-sea soundscapes around hydrothermal vents?

Birds sing to be heard, but how do they cope with increasing noise levels? Which species persist in cities and why? And do they thrive or suffer in the urban soundscape?

On Thursday 24 November 2016 Moses George will defend his PhD dissertation ‘Legal Implications of Airport Privatization in India’. The defence will commence at 11.15 hrs, in the Academy Building of Leiden University. The Supervisors are Professor Pablo Mendes De Leon and Professor Brian F. Havel (DePaul…

Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper…

She narrowly defied bureaucracy and spent days angling for cod. In the North Sea, marine biologist Inge van der Knaap discovered that noise significantly disturbs fish behaviour. ‘There is now a lot of attention for underwater noise.’

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

The SAPPAO project aims to optimise the accuracy and reliability of predicting scheduled flight times. The full name of the project is 'A Systems Approach towards Data Mining and Prediction in Airlines Operations'.

Fish populations in lakes and rivers have declined in recent decades. This is probably due to light and noise pollution. The Horizon Europe grant enables ecologist Hans Slabbekoorn to investigate this and improve the situation for migrating fish. In order to do so, a seven-metre-long swimming tunnel…

On 16 December 2021, Lisanne van Houten defended the thesis 'Flexing the Slot Regime'. The doctoral research was supervised by Prof. P. Mendes de Leon and Prof. L. Pierallini (Luiss University Of Rome).

Human activity at sea makes a terrible racket. To what extent does this disturb marine animals? PhD candidate Annebelle Kok studied the effect on harbour porpoises, long-finned pilot whales and their prey, and discovered the sheer complexity of the problem. PhD defence on 12 November.

Conference

The focus of this thesis is on the technical methods which help promote the movement towards Trustworthy AI, specifically within the Inspectorate of the Netherlands.

To what extent is sound a stressor to fish? And are behavioural and physiological phenotypes equally sensitive to disturbance by noise pollution?

This thesis described the development of novel scanning tunneling microscopy techniques to investigate strongly correlated electronic states in quantum matter.

‘Even at the deepest point in the ocean you can still hear the noise from boats,' says biologist Hans Slabbekoorn. ‘And that's while sound is the most important means of communication for underwater life.' What is the effect of all that underwater noise on fish and other animals? Slabbekoorn is on board…

Hans Slabbekoorn researches animal sounds and the effect of the noise we humans make on these animals. He is also committed to making his discipline more diverse.

Do babies and toddlers thrive more in a noisy or quiet day care centre? Research by specialist in Education and Child Studies Claudia Werner shows that children feel most comfortable in an environment where there is a little noise. With this kind of research, the method of analysis is very important.…

Leiden is easily accessible by public transport. The city is ideally situated just a stone's throw from major cities like The Hague and Amsterdam. For those travelling to Leiden by plane, we are pleased to announce that KLM offers discounts for Speech Prosody attendees.

The Kroese-Duijsters symposium will be held in the heart of the Leiden city centre.

In ancient Greece and Rome, nighttime encompassed a distinctive array of cultural values that went far beyond the inversion of daytime. Night was a mythological figure, a locus of specialized knowledge, a socially significant semantic space in various literary genres, and a setting for unique experi…

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

When designing public spaces, noise is often a neglected issue. Architects and urban planners know little about it; noise experts see it mainly as a problem that should be solved simply by reducing the volume. University lecturer Andrea Giolai (LIAS), researcher Kevin Toksöz Fairbairn (ACPA) and Professor…

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…
