“…The acoustics (reverberation time and diffusivity) of the room were manipulated to match those found within a commercial truck cab. Truck noise was presented at 74.9 ± 0.5 dBA, typical of the noise levels in newer trucks (Morrison & Casali, 1994). The signals were first adjusted digitally to ensure that they were perceived to be equally loud.…”

This simulator-based study examined conventional auditory warnings (tonal, nonverbal sounds) and auditory icons (representational, nonverbal sounds), alone and in combination with a dash-mounted visual display, to present information about impending collision situations to commercial motor vehicle operators. Brake response times were measured for impending front-to-rear collision scenarios under 6 display configurations, 2 vehicle speeds, and 2 levels of headway. Accident occurrence was measured for impending side collision scenarios under 2 vehicle speeds, 2 levels of visual workload, 2 auditory displays, absence/presence of mirrors, and absence/presence of a dash-mounted iconic visual display. For both front-to-rear and side collision scenarios, auditory icons elicited significantly improved driver performance over conventional auditory warnings. Driver performance improved when collision warning information was presented through multiple modalities. Brake response times were significantly faster for impending front-to-rear collision scenarios using the longer headway condition. The presence of mirrors significantly reduced the number of accidents for impending side collision scenarios. Subjective preference data indicated that participants preferred multimodal displays over single-modality displays. Actual or potential applications for this research include auditory displays and warnings, information presentation, and the development of alternative user interfaces.

“…There are two cases when these systems break down: when the noise falls in the same frequency range as speech and when the noise itself is unwanted speech [20]. Since background speech is the most difficult type of noise for humans to filter out [18], this is a very serious issue.…”

Abstract. An often-heard complaint about hearing aids is that their amplification of environmental noise makes it difficult for users to focus on one particular speaker. In this paper, we present a new prototype Attentive Hearing Aid (AHA) based on ViewPointer, a wearable calibration-free eye tracker. With AHA, users need only look at the person they are listening to, to amplify that voice in their hearing aid. We present a preliminary evaluation of the use of eye input by hearing impaired users for switching between simultaneous speakers. We compared eye input with manual source selection through pointing and remote control buttons. Results show eye input was 73% faster than selection by pointing and 58% faster than button selection. In terms of recall of the material presented, eye input performed 80% better than traditional hearing aids, 54% better than buttons, and 37% better than pointing. Participants rated eye input as highest in the "easiest", "most natural", and "best overall" categories.

“…Morrison and Casali (1994) explored synthesized speech warnings used by drivers with normal hearing and impaired hearing in noisy commercial truck cabs. These researchers found that auditory synthesized speech designed for use in heavy truck cabs must contend with the high noise levels already present in these vehicles and that truck cab noise levels could have a degrading effect on the intelligibility of synthesized voice messages and could pose a substantial risk to drivers.…”
