Transportation vehicle development cycles must be reduced due to competitive reasons which require a reduction in time and costs. In the past, and still today, development processes in acoustic engineering consist of measurements, analyses, modifications and verification on prototypes in several loops. This procedure is timeand cost consuming. On the other hand the acoustic comfort needs to be ...

School teachers have an elevated risk of voice problems due to the vocal demands in the workplace. This manuscript presents the results of three studies investigating teachers' voice use at work. In the first study, 57 teachers were observed for 2 weeks (waking hours) to compare how they used their voice in the school environment and in non-school environments. In a second study, 45 participant...

Studying the impact of various factors on environmental perception is crucial because humans live in an environment where these interact and blend. The thermal-acoustic major factor that affects overall urban parks. This study focuses parks subtropical region, with Xihu Park Fuzhou, China, as research area. Through measurements questionnaires, this explores effects subjective evaluation (therma...

Araştırmada bir devlet ilkokulunun akustik konfor düzeyi nesnel ve öznel verilerle değerlendirilmeye çalışılmıştır. Çalışmada karma desen yöntemi kullanılmıştır. Nesnel veri olarak desibelmetre ile okulun gürültü sınıfların reverberasyon süresi ölçülmüştür. Öznel okul yöneticisi öğretmenler konforu hakkında görüşmeler yapılmıştır. Desibelmetre yapılan ses reveberasyon ölçüm sonuçları, yönetmeli...

We investigate strategic information transmission with communication error, or noise. Our main finding is that adding noise can improve welfare. With quadratic preferences and a uniform type distribution, welfare can be raised for almost every bias level by introducing a sufficiently small amount of noise. Furthermore, there exists a level of noise that makes it possible to achieve the best pay...

Assessment of visual acuity is a well standardized procedure at least for expert opinions and clinical trials. It is often recommended not giving patients feedback on the correctness of their responses. As this viewpoint has not been quantitatively examined so far, we quantitatively assessed possible effects of feedback on visual acuity testing. In 40 normal participants we presented Landolt Cs...

Current literature and guidelines on sustainable design often debate the advantages of natural ventilation (NV) mechanical (MV) indoor environment energy consumption. The present systematic review explores existing comparing NV MV comfort well-being points view. findings emphasize that thermo-hygrometric is main driver occupants’ behavior, while mainly led by air quality targets. Moreover, more...
