The human voice calling your name is a strong auditory cue for most people, but a response is still inconsistent within ACL 1.2
Other alerting sounds may include sirens, buzzers, bells, clickers, a child crying, a fog horn, sneezing, coughing, clapping hands, whistles, duck calls, door slams, door bells and dogs barking. The only response may be to look toward the sound in about 20 seconds.
Because so many alerting sounds are self-protective signals and clickers are hard to find, bells are highly valued in ACL 1. Choir bells with notes that are in tune are a good investment. The metronome sound that is set to the speed of their heart rate is replacing clickers. Most smart phones have a metronome. Additional positive auditory cues that get a response in ACL 1.2 are needed. Please share if you find one.
Positive auditory sensations are hard to find because the sounds have to be so strong. Hearing impairments that would benefit from nearly all hearing aids are not noticed by people functioning in ACL 1.
