In this work, the experimental design was presented in the form of a replica, in which a sample of sixty university students was evaluated in order to determine the effect caused by reverberation time and background noise on the cognitive processes of memory, attention and executive functions, seeking to contrast the results obtained in previous researches. Statistical analysis is presented in order to relate the effect of these acoustic parameters. Five psychological instruments were applied where four of these psychological instruments were auralized taking into account the acoustic conditions measured and the hypothetical treatment of the mini auditorium 2 of the University of San Buenaventura, San Benito Medellín.
For the application of the test, the recording room of studio A of the University of San Buenaventura Medellín was used and the psychological instruments were reproduced using the Opsodis binaural reproduction system as specified in the connection diagram of section VII.A and the distribution within the recording room as shown in Figure 8.
It was found that the results found in previous theses where the impact of reverberation time and background noise on cognitive processes was evaluated are similar, corroborating in the same way the foreign investigations, where it is proven that background noise and reverberation time significantly affect attention, memory and executive functions, being reverberation time the most affected acoustic parameter. High background noise causes interference in the communication of verbal messages, causing the individual to remain in an unnecessarily high attention span, which can have negative health effects such as fatigue and stress[1]. The long reverberation time in turn causes loss of speech intelligibility, i.e. verbal messages are partially understood or sometimes confused |
