Wearable device Product Sonic Branding

We make a wearable device that is used by elderly people, their families and caregivers both at home and in group living facilities. Our device has a codec/speaker and we want to create a sonic brand for the various sounds from our product: Some examples are: Startup sound Assistance needed button push sound (repeating sound) Sound preceding an audio message Staff providing assistance sound Person in prohibited area sound (repeating sound) Cancel alert sound Volume Up sound Volume down sound On charger sound Fully charged sound Restarting sound Factory reset sound Configuration mode sound Pairing mode sound The elderly are in the age of 65 and up and the staff age can range from 21 to 65. The elderly age must be taken into account for designing the sounds, particularly in terms of frequencies that elderly cannot hear clearly. The sounds must be threatening, non-frightening and must be relaxing, playful and memorable. The sounds represent our core values of helping the elderly age independently, economically, longer and better.
