TL;DR: In this article, the influence of railway noise and vibration levels on railway annoyance was investigated under laboratory conditions and no influence of vibration level on railway noise annoyance was detected, only when the vibration level was high (L V eq = 116 dB).

TL;DR: In this paper , the relationship between sound quality and first order physical parameters in rotor systems is investigated within the framework of a perception-driven engineering approach to aid design, and a psychoacoustic annoyance model is formulated.
Abstract: The aviation sector is rapidly evolving with more electric propulsion systems and a variety of new technologies of vertical take-off and landing manned and unmanned aerial vehicles. Community noise impact is one of the main barriers for the wider adoption of these new vehicles. Within the framework of a perception-driven engineering approach, this paper investigates the relationship between sound quality and first order physical parameters in rotor systems to aid design. Three case studies are considered: (i) contra-rotating versus single rotor systems, (ii) varying blade diameter and thrust in both contra-rotating and single rotor systems, and (iii) varying rotor-rotor axial spacing in contra-rotating systems. The outcomes of a listening experiment, where participants assessed a series of sound stimuli with varying design parameters, allow a better understanding of the annoyance induced by rotor noise. Further to this, a psychoacoustic annoyance model optimised for rotor noise has been formulated. The model includes a novel psychoacoustic function to account for the perceptual effect of impulsiveness. The significance of the proposed model lies in the quantification of the effects of psychoacoustic factors, such as loudness as the dominant factor, and also tonality, high frequency content, temporal fluctuations, and impulsiveness on rotor noise annoyance.

TL;DR: One goal of a hearing instrument fitting is to minimize the annoyance factor of background noise, which may be so great that it prevents patients from using the hearing instrument long enough for acclimatization to occur.
Abstract: Background noise has long been a major nemesis for hearing instrument wearers. Not only does it reduce speech understanding, but in many cases the noise creates annoyance, making hearing instrument use an overall unpleasant experience. Research has shown that new hearing aid users find background noise significantly more annoying than when they were unaided.1-3 In fact, new users rate background noise as being more annoying than do persons with normal hearing. This is true even when the output of the hearing instrument is carefully adjusted to fall below the patient’s loudness discomfort level (LDL). This finding suggests that the problem is not uncomfortably loud noise, but noise in general.4 To some extent, this is due to the patient’s previously reduced loudness perception of these noises. While it is possible that long-term auditory acclimatization will help hearing aid wearers adapt to these noises,5 it is also possible that the annoyance will prompt the wearer to stop using the hearing instruments.6 That is, the annoyance level may be so great that it prevents patients from using the hearing instrument long enough for acclimatization to occur.Therefore, one goal of a hearing instrument fitting is to minimize the annoyance factor of background noise. IDENTIFYING THE PROBLEM In determining how best to reduce the annoyance of noise, it is first important to consider the range of noises that hearing instrument wearers experience in their daily lives. For example, how do these noises vary in intensity and duration? Some hearing aid users report significant annoyance from loud continuous noises such as that of a vacuum cleaner, while others are annoyed by transient-duration soft sounds such as computer key strokes. Hernandez et al. recently reported on the extent of annoyance from different types of noises, and on the different noises commonly encountered by hearing aid users.7 The distribution of the ratings for the various environmental noises is shown in Figure 1. Observe that the types of noises experienced were distributed relatively equally throughout the different categories, with very similar distribution for the three duration times summed across loudness levels. Importantly, 33% of the environmental sounds reported annoying were transient in duration. The participants in the research by Hernandez et al. also rated the annoyance level of the different sounds.7 As might be expected, the greatest annoyance was reported for loud continuous sounds (see Figure 2). Observe, however, that even transient noises were rated as quite bothersome (5.8 averaged across loudness levels), and loud transient sounds were not significantly less annoying than those of medium or long duration.

TL;DR: In this article, the influence of the temporal characteristics of varying noise levels such as aircraft noise on noise assessment is considered and corrections to account for subjective response to temporal characteristics may be carried out in a simple and effective manner and a corrected form of the equivalent noise level is the appropriate measure to employ for land use planning.
