This research project investigates whether ensemble statistics atomic number 18 to a fault possible in the sound intensity domain. It has been established that slew re take multiple objects as ensembles in many types of stimuli in optical domain. Also, some studies investigated this ability in auditory domain on frequency. The present study aims to show that people batch also represent a set of varying decibels as an ensemble. This ability might be significant given that in daily life people are loose to multiple levels of sound intensities and extracting summary statistics can be beneficial to channelize attention to more salient sounds, like rising sound which can indicate an approaching target, among many others. To investigate whether people represent contrastive decibels as ensembles this study used dynamic exposure in temporal role sequences and to get finer grained responses used a response method in which participants generated their own instead of choosing among alte rnatives. Since the relationship between decibel increase and comprehend intensiveness increase is not linear but it follows Stevens power rule, it is pass judgment that participants responses will provide a better fit with Stevens exponent for loudness in perceiving the medium loudness of sounds. In daily life, along with unmarried stimuli, people encounter with crowds of stimuli and they are satisfactory to perform in the fount of the abundance of stimuli. Given that sensory systems capacity is limited to a real amount of information, (Alvarez & Cavanagh, 2004), instead of representing every single object individually, there may be another way for representing group of items (Ariely, 2001). Ensemble re insertions, which can be defined as representations that give the compressed summary statistics... ...rentiating softer sounds would not be likely, a type of dynamic display should be used. For this study, discrete presentation of individual sounds in following temporal se quences will be used. Also, as for the response selection, people will generate their own responses. This, as also suggested by Haberman and Whitney (2009), allows getting a finer grained response from the participants. Hence, this study proposes that as it is the case for many other properties of various stimuli types, humans should be able to extract summary statistics of a set of sound decibels, which is a primaeval property of our acoustic environment, but this averaging should follow Stevens power function on loudness. This research project first explores whether this is the case, whether people can find the average decibel of sounds that are presented dynamically in temporal sequences.
