Perception of reverberation length in rooms with reverberation enhancement systems.

This study examined the perception of reverberation length in rooms equipped with a reverberation enhancement system (RES). In the past, many acousticians have studied the correlation between subjective reverberation ratings and objective criteria in concert halls; the effect of RES on these ratings has not been thoroughly investigated. The decay of acoustic energy in rooms with RES has double-slope characteristics, which is different from most impulse responses recorded in rooms without such a system.

Home Monitoring of Asthma Exacerbations in Children and Adults With Use of an AI-Aided Stethoscope.

Purpose: The advent of new medical devices allows patients with asthma to self-monitor at home, providing a more complete picture of their disease than occasional in-person clinic visits. This raises a pertinent question: which devices and parameters perform best in exacerbation detection?

Methods: A total of 149 patients with asthma (90 children, 59 adults) participated in a 6-month observational study. Participants (or parents) regularly (daily for the first 2 weeks and weekly for the next 5.

Artificial Intelligence Approach to the Monitoring of Respiratory Sounds in Asthmatic Patients.

Effective and reliable monitoring of asthma at home is a relevant factor that may reduce the need to consult a doctor in person. We analyzed the possibility to determine intensities of pathological breath phenomena based on artificial intelligence (AI) analysis of sounds recorded during standard stethoscope auscultation. The evaluation set comprising 1,043 auscultation examinations (9,319 recordings) was collected from 899 patients.

The accuracy of lung auscultation in the practice of physicians and medical students.

Background: Auscultation is one of the first examinations that a patient is subjected to in a GP's office, especially in relation to diseases of the respiratory system. However it is a highly subjective process and depends on the physician's ability to interpret the sounds as determined by his/her psychoacoustical characteristics. Here, we present a cross-sectional assessment of the skills of physicians of different specializations and medical students in the classification of respiratory sounds in children.

Practical implementation of artificial intelligence algorithms in pulmonary auscultation examination.

Lung auscultation is an important part of a physical examination. However, its biggest drawback is its subjectivity. The results depend on the experience and ability of the doctor to perceive and distinguish pathologies in sounds heard via a stethoscope.

Audio-visual interactions in environment assessment.

The aim of the study was to examine how visual and audio information influences audio-visual environment assessment. Original audio-visual recordings were made at seven different places in the city of Poznań. Participants of the psychophysical experiments were asked to rate, on a numerical standardized scale, the degree of comfort they would feel if they were in such an environment.
