Report in Danish extended summary in English The report describes an update and gives some administrative guidelines for the method described in ISO/DPAS 1996-3: Objective method for the measurement of prominence of impulsive sounds and for adjustment of LAeq This is the third and final part of a project on the adjustment (penalty) to the measure...

The FAMOS project is about analysing and testing if non-acoustic moderators for noise annoyance can be a promising tool for obtaining an additional supplement to other noise and annoyance mitigation measures to reduce the annoyance without reducing the noise level further. Scientific methods have been used to find, extract, and analyse data and tur...

Background: The potential health effects related to wind turbine noise (WTN) have received increased focus during the past decades, but evidence is sparse. We examined the association between long-term exposure to wind turbine noise and incidence of atrial fibrillation (AF). Methods: First ever hospital admission of AF amongst 28,731 female nurs...

Background Epidemiological studies suggest that road traffic noise increases the risk of stroke. Similar effects may be expected from wind turbine noise ( WTN ) exposure, but epidemiological evidence is lacking. The present study investigated the association between long‐term exposure to WTN and the risk for stroke. Methods and Results First‐ever...

Background: Evidence on the association between road traffic noise and diabetes risk is sparse and inconsistent with respect to how confounding by air pollution was treated. Objectives: In this study, we aimed to examine whether long-term exposure to road traffic noise over 25 years is associated with incidence of diabetes, independent of air po...

Sensory Evaluation of Sound provides a detailed review of the latest sensory evaluation techniques, specifically applied to the evaluation of sound and audio. This three-part book commences with an introduction to the fundamental role of sound and hearing, which is followed by an overview of sensory evaluation methods and associated univariate and...

Background Growing evidence supports the concept that traffic noise exposure leads to long-term health complications other than annoyance, including cardiovascular disease. Similar effects may be expected from wind turbine noise exposure, but evidence is sparse. Here, we examined the association between long-term exposure to wind turbine noise and...

Background: Exposure to road traffic noise was associated with increased risk of estrogen receptor (ER)-negative (ER-) breast cancer in a previous cohort study, but not with overall or ER-positive (ER+) breast cancer, or breast cancer prognosis. We examined the association between long-term exposure to road traffic noise and incidence of breast ca...

Background/aim Exposure to road traffic noise has been linked to adverse health effects, including cardiovascular diseases (CVD), however, evidence is inconsistent. In this study we examined the association between long-term exposure to road traffic noise and incidence of myocardial infarction (MI). Methods We used the data from a nationwide Danis...

In this study the characteristics of compact loudspeakers in a stereo setup positioned in a standardized listening room were investigated. Perceptual evaluations of eleven loudspeakers were conducted on the basis of six selected sensory descriptors, chosen by experienced listeners during consensus meetings. Based on an analysis of the perceptual ev...

This study tested a framework for modelling of sensory descriptors (words) differentiating headphones. Six descriptors were included in a listening test with recordings of the sound reproductions of seven prototype headphones. A comprehensive data quality analysis investigated both the performance of the listeners and the suitability of the descrip...

A literature study was conducted focusing on maximizing objectivity of results from listening evaluations aimed at establishing the relationship between physical and perceptual measurements of loudspeakers. The purpose of the study was to identify and examine factors influencing the objectivity of data from the listening evaluations. This paper add...

Sound quality is an important aspect in many sound reproduction applications. In recent years sensory evaluation techniques have been gaining popularity for the detailed perceptual assessment of device sound characteristics. From the literature, 100s of descriptors can be found to describe the nature of sound quality and this often becomes the focu...

Summary This report addresses external warning sounds for hybrid and electric vehicles. The purpose of adding external sound at low speeds is to minimise the risk from these quiet vehicles for pedestrians, cyclist and blind persons. The main perspective of the report is to describe signals and systems that minimises the risk and causes as low noise...

Since 1979 the Danish Environmental Protection Agency's Reference laboratory for noise measurements have arranged proficiency testing for the around 30 approved Danish laboratories that are measuring environmental noise. Many of these "comparison measurements" have included objective analysis of the prominence of audible tones according to the Join...

Sounds may be characterized by objective perceptive attributes (for which there may exist physical metrics) or by subjective (affective or connotative) attributes. This paper will deal with the perceptive attributes. Within product sound quality the metrics for classical the psycho-acoustic attributes (loudness, sharpness, roughness and fluctuation...

When communicating verbally about sound, when making profile diagrams, and when making listening tests (e.g. pairwise comparison and semantic differential) words are needed to de- scribe and discriminate and scale the characteristics of the sounds. This report contains a list of sound-describing words – a “Lexicon”. The purposes of the Lexicon are:...

ENQUETE: Torben Holm Pedersen: Lyd – objektivt og subjektivt

It is recognised that A-weighted measurements of sound pressure levels and sound power levels alone are insufficient for measurements in relation to product sound quality and noise annoyance potential. This has led to increasing interest in measures in closer agreement with human sound perception as e.g. loudness, sharpness roughness. Equipment, wh...

The interest in using listening tests as both an objective and a subjective measuring tool is increasing. There are no generally accepted guidelines for making listening tests so the results are seldom comparable, and there is a risk that `newcomers' in this field make fundamental methodological errors. Part 2 of this NORDTEST guideline is meant as...

This conference paper is the first publication on the relation between sound level caused by operating wind turbines on the one hand, and perceptions of annoyance among nearby residents. On locations in Denmark, the Netherlands and Germany the actual annoyance caused by wind turbine noise was investigated. Residents of communities living around exi...

As part of the COST Action TU0901 WG 2 activities a listening test was made on the annoyance potential of airborne noise from neighbours heard through walls. 22 assessors from 11 countries rated six simulated walls with four types of neighbour noise online at the assessor's premises using the ISO/TS 15666 annoyance scale. A simple "calibration" pro...
