“…In residential buildings, noise levels above 70 dB(A) usually cause discomfort and make people sick (Neitzel, Heikkinen, Williams, Viet, & Dellarco, 2015). In this study, the majority of the measured BN levels were below 50 dB(A).…”

There is little empirical evidence in the literature about the indoor environmental quality performance of residential buildings in general and of social housing in particular. To address this problem, this study used a mixed-method approach to evaluate the indoor environmental quality performance of 17 green low-income single attached family houses in Brandon, Manitoba, Canada. Questionnaires were administered to occupants to assess their snapshot and long-term satisfaction with the indoor environment. In addition, snapshot measurements were carried out to evaluate the indoor environmental quality factors of thermal comfort, indoor air quality, lighting and acoustics. Occupants' snapshot satisfaction was categorized into two groups (i.e. satisfied/comfortable or dissatisfied/uncomfortable) and compared with snapshot measurements. The results showed the measured IEQ parameters were well below recommended threshold levels. Further, occupants with higher snapshot satisfaction were generally exposed to relatively lower levels of indoor pollutants. A statistically significant difference was found in PM10 level only between the snapshot satisfied and snapshot dissatisfied groups of occupants. Apparent sound transmission classes were below the standard reference value of 50, suggesting potential problems in noise attenuation within different spaces in each apartment and between apartments. The findings of this study could help governments implement green shadowing for public-housing and also renovate existing houses using the same principles.

“…The robustness of the microphone, accelerometer and the applications used to acquire sound and vibration has been proven by previous researches [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. At the same time, we also evaluated the measuring instruments to accommodate the British standard BSEN 61672 in our previous study [8] by comparing the six sound measurement applications and six vibration measurement applications yielding that the DecibelX for sound measurement is outperforming other applications.…”

“…Multiples research and government institutes have adopted the microphone of phones to monitor noise pollution monitoring [15][16][17][18] leading to the growing development of many mobile apps for measuring sound levels such as NoiseSPY [19], EarPhone [20] and NoiseTube [21]. The reliabilities of these applications have been assessed outside and inside a laboratory [22][23][24][25][26].…”

In 2011 the percentage of the American population affected by Noise Induced Hearing Loss (NIHL) was 15.3%. Unlike most forms of hearing loss, this can be prevented by limiting exposure to certain magnitudes of noises for varying amounts of time. The present study aims to assess the sound which can contribute to NIHL given off from dropping free weights using six calibrated smartphones in the gym at the University of Birmingham. This report sets out to measure the noise and vibration given off by dropping loaded barbells at the top of a deadlift. By conducting these tests, it can be assessed whether the sound given off from dropping free weights in the gym could be contributing to NIHL. A relationship between drop weight and the vibration is also be constructed. For vibration, it is found that vibration level (m/s 2 ) increased with drop weight, whereas the average noise level for each drop weight only varies by a range of 4.4 dB between 102.7 dB and 98.3 dB. There is no correlation shown by these results between sound level and drop weight, however, all the sound levels recorded are over 85 dB leading to NIHL. This study reminds us that measures need to be taken to reduce the sound level from the dropping of loaded barbells in the University of Birmingham Sports and Fitness Centers

ZUsAmmenfAssUng Die Nutzung mobiler Informations-und Kommunikationstechnologie im Kontext medizinscher und gesundheitsnaher Dienstleistungen, z. B. in Form von Apps, gewinnt, leider jedoch häufig unter Missachtung notwendiger Qualitätskriterien, immer mehr an Bedeutung. So erscheint es wichtig, dass neben einer die Anwendungssoftware kontrollierenden Instanz möglichst hoch qualifizierte Akteure des Gesundheitswesens bei der Erstellung mitwirken. Schon aus Haftungsgründen muss der beratende Arzt eine hohe Sorgfalt bei der Auswahl und Empfehlung einer App walten lassen, gerade auch in Anbetracht der Tatsache, dass nur wenige Apps als Medizinprodukt zertifiziert sind. Auf dem Markt gibt es eine große Anzahl an medizinischen Apps, wobei nur ein geringer Anteil dieser auf den Fachbereich HNO-Heilkunde entfällt. Prozentual sind die Teilbereiche Audiologie, Schlafmedizin und Allergologie am häufigsten vertreten. Obwohl sich der Fachbereich der HNO-Heilkunde zunehmend mit dieser Thematik wissenschaftlich auseinandersetzt, fehlt, wie generell bei vielen medizinischen Apps, eine wissenschaftliche Evidenz der Inhalte und Ergebnisse. Es gibt jedoch für Anwender weitere Möglichkeiten, medizinische Apps nach definierten Qualitätskriterien in verschiedenen Kategorien, wie z. B. Funktionalität, Wissenschaftlichkeit, aber auch Datenschutz, zu beurteilen. Keine der mittels eines solchen Bewertungstools evaluierten Apps erfüllte alle geforderten Kriterien, dem Anwender steht jedoch hiermit ein Instrument zur besseren Einschätzung der Anwendungssoftware zur Verfügung. Im Rahmen des Entwicklungsprozesses einer medizinischen App für den HNO-Bereich war es jedoch möglich, die Qualitätskriterien zu berücksichtigen. Zusammenfassend soll die vorliegende Arbeit einen Überblick über Thema "Apps in der HNO-Heilkunde" ermöglichen mit dem Ziel, dieses moderne Hilfsmittel nutzbringend einsetzen zu können. ABsTRAcTThe implementation of mobile information and communication technology in the field of health services, e. g. in the form of apps, is becoming increasingly important. Unfortunately, the necessary quality criteria are often mising. Thus, it seems important, that in addition to an app controlling authority highly qualified health care professionals participate in the development of these applications. For reasons of liability, however, the physician must exercise great caution in the selection and recommendation of medical apps, especially considering, that only a few apps are certified as medical devices. There are a large number of medical apps on the market, with only a small proportion being assigned to the field of otorhinolaryngology. The areas of audiology, sleep medicine and allergology are most frequently represented. Althouhgh there is increasing scientific work on this topic in the field of otorhinolaryngology, there is a lack of scientific evidence of contents and results, as is generally the case of medical apps.However, there are other possibilities for users to rate medical apps regarding defined qualitiy criteria such as f...
