Introduction to Acoustic Assessment

Electroencephalography (EEG) and psychoacoustic assessment was undertaken at baseline and following 3 months of each masking sound.

Acoustic assessment has the potential to provide critical, objective information during telepractice, yet its validity via telepractice is currently unknown.

These concepts pose new challenges for the vibro-acoustic assessment of cabin structures and the associated noise impact on passengers.

The SVF gel was transplanted into the vocal fold muscle and the paraglottic space, and subjective and perceptual assessments, aerodynamic and acoustic assessments, and a videostroboscopic assessment were evaluated pre- and postoperatively at 1day, 12 months and 18 months.

This work demonstrates the potential magnitude of differences among vessels and highlights the need to identify and account for or otherwise control for these effects when monitoring or managing fisheries through standardized hydroacoustic assessments surveys.

Auditory perceptual analysis, acoustic assessment, aerodynamic assessment and self-assessment protocol were conducted before the intervention and one week after the last intervention, and the differences before and after interventions within each group and between groups were compared.

This chapter will focus on reviewing the psychoacoustic assessment of tinnitus, its relationship to cognitive and behavioral aspects of tinnitus, and its neuropathophysiology.

Acoustic assessment has the potential to provide critical, objective information during telepractice, yet its validity via telepractice is currently unknown.

The article, thus, presents, validates and illustrates the potential of linear acoustic analysis toward the acoustic assessment and optimization of RFPs.

The aim of the work is to develop methods for acoustic assessment of the stress-strain state, the elastic moduli and the properties anisotropy of pipeline material and to study these characteristics in different sections of main pipelines using a device based on contactless EMA transducers.

This novel forward-viewing PAE probe could provide new opportunities for the photoacoustic assessment of tumours in the liver, cancer in the GI tract and guiding minimally invasive procedures in abdominal surgery and foetal medicine.

This paper presents the results of the aerodynamic and aeroacoustic assessment for a vertical axis wind turbine (VAWT).

This methodology opens up promising new perspectives in the acoustic assessment of habitat quality and monitoring landscape modification.

The AVO guide recommends an approach to acoustic assessment that takes regard of the interdependence of provisions for external noise ingress, ventilation and overheating.

The perceptual and acoustic assessment of the voice showed the disorders of voice quality (dysphonia), including hoarseness, roughness, and fatigue were likely caused by the disturbance of vocal folds vibrations and insufficiency of glottal closure.

The performance of the purposed system is evaluated by computer simulation, and the perceptual loudness is selected as a performance criterion for the psychoacoustic assessment of residual noise.

No statistically significant intergroup diferences were found in self-reported voice or acoustic assessment.

The responses of the psychoacoustic assessment of tinnitus (intensity, frequency, minimum masking level and loudness discomfort level for pure tone and speech), as well as the Tinnitus Handicap Inventory (THI) questionnaire, and the visual analogue scale (VAS) were compared between 15 patients with tinnitus and peripheral hearing loss (group I) and 16 adults with normal hearing (group II).

RESULTS For acoustic assessment, the percentage of phonatory breaks (PBs) of connected reading and the percentage of aperiodic segments and frequency shifts (FS) of vowel and reading in patients with ADSD were significantly worse than controls, the mean harmonics-to-noise ratio and the fundamental frequency standard deviation of vowel as well.

The responses of the psychoacoustic assessment of tinnitus (intensity, frequency, minimum masking level and loudness discomfort level for pure tone and speech), as well as the Tinnitus Handicap Inventory (THI) questionnaire, and the visual analogue scale (VAS) were compared between 15 patients with tinnitus and peripheral hearing loss (group I) and 16 adults with normal hearing (group II).

The sound was evaluated with open source software PRAAT for the acoustic assessment.

This paper presents an integrated approach for the aeroacoustic assessment of four-dimensional rotorcraft operations.
