Novel auditory alerts that foster efficient detection and discrimination in complex auditory environments: Dual-task conditions

In many complex auditory environments, auditory alerts must be perceived and distinguished accurately while distractions are mitigated. Previously, we measured detection and discrimination performance using four novel alerts: one pair of narrowband and one pair of broadband alerts. Within each pair, one alert was perceived as consonant (labeled “friendly”) and one as dissonant (labeled “enemy”). The alerts were presented along with maskers …
