TI  - Impact of non-individualised head related transfer functions on speech-in-noise 
      performances within a synthesised virtual environment.

AB  - When performing binaural spatialisation, it is widely accepted that the choice of 
      the head related transfer functions (HRTFs), and in particular the use of 
      individually measured ones, can have an impact on localisation accuracy, 
      externalization, and overall realism. Yet the impact of HRTF choices on 
      speech-in-noise performances in cocktail party-like scenarios has not been 
      investigated in depth. This paper introduces a study where 22 participants were 
      presented with a frontal speech target and two lateral maskers, spatialised using 
      a set of non-individual HRTFs. Speech reception threshold (SRT) was measured for 
      each HRTF. Furthermore, using the SRT predicted by an existing speech perception 
      model, the measured values were compensated in the attempt to remove overall 
      HRTF-specific benefits. Results show significant overall differences among the 
      SRTs measured using different HRTFs, consistently with the results predicted by 
      the model. Individual differences between participants related to their SRT 
      performances using different HRTFs could also be found, but their significance 
      was reduced after the compensation. The implications of these findings are 
      relevant to several research areas related to spatial hearing and speech 
      perception, suggesting that when testing speech-in-noise performances within 
      binaurally rendered virtual environments, the choice of the HRTF for each 
      individual should be carefully considered.
