Short-term exposure to high-intensity sound induces hearing loss and apoptosis in guinea pigs

INTRODUCTION It is well-known that noisy environments are inevitable because of the rapid development of industrialization, and noise-induced hearing loss (NIHL) has become a severe disease worldwide (Ide and Morimitsu, 1990; Akdogan et al., 2009; Jacob et al., 2013). However, high-intensity sound exposure, which may not occur commonly in the environment, has been transformed as a novel non-lethal weapon that can be used by authorities to disperse crowds. Hearing detection is the most direct

THE USE OF ARTIFICIAL NEURAL NETWORKS IN THE ESTIMATION OF THE PERCEPTION OF SOUND BY THE HUMAN AUDITORY SYSTEM

The human auditory system perceives sound in a much different manner than how sound is measured by modern audio sensing systems. The most commonly referenced aspects of auditory perception are loudness and pitch, which are related to the objective measures of audio signal frequency and sound pressure level. Here we describe an efficient and accurate method for the conversion of the sensed factors of frequency and sound pressure level to perceived loudness and pitch. This method is achieved

ACOUSTIC EVALUATION OF A NEW MODULAR SYSTEM FOR GREEN ROOFS AND GREEN WALLS

, variety and height of plants, affect the sound absorption of a modular system for green surfaces in simulated conditions. The results show that introduction substrate (S2) can improve the weighted sound absorption coefficient in 15% and the addition of plants (S3) improves it 20% more. However, if a variety of smaller and higher plants is used (S4) the weighted sound absorption coefficient (αw) can reach to 0.80 and an absorption class B can be obtained.

Sound-Separation System using Spherical Microphone Array with Three-Dimensional Directivity—KIKIWAKE 3D: Language Game for Children

Mixed sounds can be separated from multiple sound sources using microphone array sensor and signal processing. We believe that promotion of interest in this technique can lead to significant future development in science and technology. To investigate this technique, we designed a language game for children called “KIKIWAKE 3D” that uses a sound-source-separation system to arouse children’s interest in this technology. However, the microphone array sensor in a previous research had a limited

DEVELOPMENT OF WIRELESS SENSOR NETWORK USING BLUETOOTH LOW ENERGY (BLE) FOR CONSTRUCTION NOISE MONITORING

In this paper the development of a Wireless Sensor Network (WSN) for construction noise identification and sound locating is investigated using the novel application of Bluetooth Low Energy (BLE). Three WSNs using different system-on-chip (SoC) devices and networking protocols have been prototyped using a Raspberry Pi as the gateway in the network. The functionality of the system has been demonstrated with data logging experiments and comparisons has been made between the different WSN systems

The Benefits of Using Echolocation to Safely Navigate Through the Environment

This study investigated participant use of echolocation skills. Specifically participants were asked to describe what methods they used to generate sound, and what echolocation assisted them to do in terms of their orientation and mobility (O&M). Contrary to previous research findings, it was found that most participants preferred to use cane tapping to generate sound. Possible reasons for this finding are discussed. Participants reported that echolocation assisted them to self-orientate

A DCT Domain Image Watermarking Method Based on Matlab

In the text, A method of image watermarking based on DCT (Discrete Cosine Transform) domain algorithm is proposed and verified in experiment by Matlab. The experimental result shows that the current method can achieve embedding with sound robustness and invisibility. From the experimental results, the quality of the watermarked image is almost no decline relative to the original.

STATISTICAL VERIFICATION OF THE REVERBERATION TIME MODELS IN SMALL BOX ROOMS

The paper presents the results of measurements and theoretical calculations for little room models. Five room models have been prepared for analysis and they were placed in a chamber adopted as reverberationless. Measurements of reverberation time in these rooms were made in two variants; first in isotropic sound field, the second in the field disturbed by elements made of mineral wool. Then for all models in both variants theoretical calculations were made by means of three models: Neubeauer

Selecting Attractor Sounds for Audio-Based Navigation by People with Vision Impairments

Research into human hearing has been ‘laboratory’ oriented in the sense that the test environments do not replicate most ‘real world’ situations (Middlebrooks & Green, 1991). It is difficult to see how such tests accurately represent ‘real world’ situations regarding sound source localisation, recognition, and navigation (walking/way-finding) performance. The research reported here was conducted during the development of an audio-based indoor navigation

A generic business process model for conducting microsimulation studies

Microsimulations make use of quantitative methods to analyze complex phenomena in populations. They allow modeling socioeconomic systems based on micro-level units such as individuals, households, or institutional entities. However, conducting a microsimulation study can be challenging. It often requires the choice of appropriate data sources, micro-level modeling of multivariate processes, and the sound analysis of their outcomes. These work stages have to be conducted carefully to obtain

Dynamically Reconfigurable Routing Protocol Design for Underwater Wireless Sensor Network

Underwater Wireless Sensor Networks (UWSN) share the common challenges of terrestrial Wireless Sensor Network (WSN), however they are significantly different from terrestrial WSN. Mainly, because acoustic wireless communication is the main physical layer technology in UWSN. Acoustic communication offers longer range, but has limitations due to low speed of sound, high error probability, limited bandwidth capacity, node mobility and 3-dimensional network architecture. Most of the ground based

Increased difficulty in the use of hearing aids in older users is related, among other things, to a reduced ability to discriminate speech not only in silence but particularly in competitive variable noise due both to their aging auditory functions and to a diminished capacity to differentiate the time factors of sounds. It is probably connected with the diminished

A behavioural modification intervention to reduce snack food consumption focusing on external situational cues: The case study you can't read between meals without ruining your appetite!

Currently, obesity is a leading threat to optimal health and wellbeing in Australia. Offsetting risks of acute and chronic disease and disability, a balanced diet offers a sound investment against premature morbidity and mortality commonly associated with obesity. Demonstrated empirically to lead to weight gain, consumption of snack foods lacking in nutritional value (“indulgences”) threatens a healthy lifestyle and is as prevalent as 90% in some populations. Thus, finding strategies
