On the annoyance caused by impulse sounds produced by small, medium-large, and large firearms

A laboratory study was designed in which the annoyance was investigated for 14 different impulse sound types produced by various firearms ranging in caliber from 7.62 to 155 mm. Sixteen subjects rated the annoyance for the simulated conditions of (1) being outdoors, and (2) being indoors with the windows closed. In the latter case, a...

Kwaliteitscontrole van paalfunderingen

Na installatie van palen voor de fundering van een gebouw wordt de eis gesteld dat het draagvermogen van de paal en de stijfheid voldoende zijn. Internationaal wordt veel meer aandacht besteed aan de controle van draagvermogen van een funderingspaal dan in Nederland. In Nederland beperken wij ons tot grondonderzoek, de ontwerpnormen en het...

On total annoyance caused by different environmental sounds: A review and suggestions for additional research

Various procedures for rating total annoyance caused by different environmental sounds have been proposed. It is explained that the adequacy of the majority of these models is very limited. A more promising weighted summation model is described in which for each single source in the combination, the sound exposure will be first expressed as the...

ATAS: het antwoord op de ASW uitdaging

Het verhaal is in gewijzigde vorm reeds eerder gepubliceerd in een informatiebulletin dat wordt uitgegeven door het Analyse en Tactisch Centrum van de Koninklijke Marine. Het is mogelijk dat de ideeën en visie in dit verhaal over ATAS niet op alle punten de ideeën en visie van de marineleiding weergeven. Dit artikel is geschreven voordat de...

A further test of relevance of ASEL and CSEL in the determination of the rating sound level for shooting sounds

In a previous study on the annoyance caused by shooting sounds [Proceedings Internoise '96, Vol. 5, 2231-2236], it was shown that an almost perfect prediction of the annoyance, as rated indoors with the windows closed, was obtained on the basis of the weighted sum of the outdoor A-weighted and C-weighted sound exposure levels [ASEL (LAE) and...

On the rating of high-energy impulsive sounds: Optimalization of a level- dependent conversion procedure with help of new field survey results

A few years ago, Schomer [Noise Control Eng. J. 42(5), 179-191 (1994)] developed a new rating procedure for high-energy impulsive sounds, in which a level-dependent conversion of the C-weighted sound exposure levels (CSELs) of the impulses into A-weighted sound exposure levels (ASELs) of equally annoying vehicle sounds was applied. In a recent...

Community response to artillery and road-traffic sounds: A new field survey

With the help of a questionnaire, subjective reactions to artillery sounds (muzzle bangs mainly from 120- and 155-mm caliber weapons, detonating high-explosive shells, and other explosions) were determined for over 400 respondents divided among 17 different residential areas. Also, for the same respondents, the subjective effects of (local) road...

A review of research on the annoyance caused by impulse sounds produced by small firearms

The present paper addresses the annoyance caused by impulse sounds produced by small firearms. Spectrally, these sounds are characterized by relatively high sound pressure levels for frequencies between about 100 and 3000 Hz. In the present literature review, the results from field, laboratory, and field-laboratory studies are considered. In all...

Greenhouse lighting side-effects: Community reaction

With the help of a questionnaire, subjective reactions to the emitted light of greenhouses were determined for about 400 respondents divided among 10 different residential areas. The amount of vertically directed greenhouse light (vertical illuminance) at the observer points ranged between 0.003 and 2 lx. The luminance above the greenhouse(s)...

Perceptual separation of simultaneous complex tones: the effect of slightly asynchronous onsets

Onset asynchrony has been put forward as one of the relevant factors in auditory scene analysis (for references, see A.S. Bregman, MIT Press, Cambridge, 1990). In the present study this issue was further investigated using a new paradigm: musically trained subjects were presented with two successive pairs of simultane-ous complex tones and they...

Annoyance caused by low frequency sounds from artillery fire: The expected effects of various training schedules

Binnen bepaalde grenzen verwachten omwonenden minder door schietgeluid te worden gehinderd indien men de oefeningen in een kleiner aantal dagen laat houden. De tijdelijke stijging van de geluidbelasting op oefendagen ten gevolge van concentratie wordt ruimschoots gecompenseerd door het aantal stille schietvrije dagen dat daar tegenover staat.

Hinder van gelijktijdig impuls-, wegverkeers- en luchtverkeersgeluid: Een kwantitatief model

Uit in het laboratorium verzamelde beoordelingen van tal van combinaties van impuls-, wegverkeers- en luchtverkeersgeluid blijkt dat met een vereenvoudigd model de totale hinder goed uit de hinder van de afzonderlijke geluidbronnen kan worden voorspeld.

Downwind propagation of artillery sounds over distances between 01 and 10 km: Empirical data

Op z'n minst voor bron-ontvanger afstanden van 0.1 tot 10 km geldt dat het geluidniveau van artilleriegeluiden lineair afneemt met de logaritme van de afstand.
