This invention relates to a system and method for promoting acoustic wellness in living communities, particularly senior living communities.
In various exemplary embodiments, the present system is designed to improve the “acoustic wellness” of various public and private spaces, particularly in assisted-living communities or facilities, although the techniques and processes described below can be used in other areas or facilities, such as facilities or locations providing hospice care, hospice centers, nursing homes, hospitals, and residences. The techniques and process described below may also be used in auditoriums, conference centers, meeting halls, convention centers, hotel meeting rooms, and other locations.
In one exemplary embodiment, the present invention comprises an acoustic assessment 100 of the common or public areas in the assisted-living community or facility. These areas are selected area-by-area 200, and include, but are not limited to, dining rooms, theatres, game rooms, and activity or multi-purpose rooms where lectures, sermons, presentations, movies, meetings, entertainment, performances and the like are conducted for individuals or groups. The entire space thus is acoustically mapped 300, with measurements of reverb time and noise level with different weightings at each table or listener location within the space. The process also measures HVAC noise, particularly white noise and air handler rumble. These measurements are done with senior-specific methods, practices and priorities. Ordinary, conventional acoustic measurements are not optimized for the hard of hearing, with or without hearing aids, or those with dementia.
A computer program models 400 the acoustics at each table or listener location in the space, and identifies speech intelligibility/reverb/decay/amplitude with and without occupants. The program then develops acoustic remediation solutions 500. These include, but are not limited to, modifications to the HVAC system to reduce white noise and air handler rumble, including modifications to mounts, ductwork baffles and air velocity. Remediation solutions also include sound-absorbing panels engineered to reduce white noise, which are then built and installed where necessary. This process can be completed for one area or multiple areas.
In yet another embodiment, the present invention comprises an assessment of sound reinforcement of lectures, presentations, parties, meetings, and the like. The loss of hearing in one or both ears, especially when compounded by Alzheimer's disease or dementia, diminishes or destroys the “Cocktail Party Effect” (i.e., the ability of a person to discern what another is saying when multiple people are speaking at once), which is essential for conversation in group or crowded settings. Special signal processing and electro-acoustic modifications are used to promote limbic engagement, such as broad dispersion loudspeakers where the dispersion is not modulated by frequency and the amplitude is not modulated by the impedance.
In several embodiments, broad dispersion loudspeakers are spaced so that there are no gaps in coverage, particularly in the vocal range between 300 and 4000 Hz. Conventional wisdom includes a midrange that when measured on axis crosses over to a tweeter between 2000 and 2500 Hz. However, any non-linearity in dispersion and amplitude between 300 and 4000 Hz at any seating position is sub-optimal for the hearing impaired, with or without hearing aids, and for anyone with dementia. These individuals simply cannot discern the voice they are trying to listen to from the background noise, revert, and sounds of others speaking.
In one embodiment, the system uses ceiling speakers with the above characteristics and placement. In another embodiment, the broad dispersion speakers are wall mounted (e.g., a HEAL line array). Every area with a listener is illuminated with all frequencies.
In one embodiments, the speakers comprise Model 15 Reference PipeDreams Line Arrays with 4-inch midrange speakers and 1-inch tweeters. The mid-range speakers handle 125-3500 Hz with no crossover in that range. This design is optimum for a wide room with a low ceiling. Closely-spaced ceiling speakers may be used in rooms with higher ceilings. All installations attach to video, and also may comprise hearing aid loops (as described below).
In yet another embodiment, the present invention comprises one or more hearing aid loops in one or more of the spaces described above (e.g., activity or multi-purpose meeting rooms). These loops comprise an inductively-coupled antenna that broadcasts directly to a “T” coil in modern hearing aids (i.e., without sound waves travelling through the air). Senior-specific signal processing is used to enhance intelligibility and the emotional appreciation of music and sounds. In one embodiment, the signal processing incorporates equalization and a euphonic harmonic circuit. The harmonic enhancement assists those with hearing loss to feel sound and music and “fill in the blanks” in their hearing.
The cochlea is populated with small hairs or cilia, which transmit sound vibrations to nerves that are arrayed along its length and curve. With hearing loss there is usually organic death or disability of these hairs and follicles along portions of the cochlea. Some frequencies are detectable and others are lost or seriously attenuated. By adding and transmitting certain harmonics corresponding to octave jumps in modern music to fundamental frequencies, the ear and brain is able to extrapolate or synthesize missing parts of sounds by sum and difference psychoacoustics. Intelligibility is enhanced, music is more enjoyable, and importantly, the opportunity for limbic (startle) response is enabled. Enhancing or restoring intelligibility is critical to diminishing isolation and loneliness. The present invention restores serum dopamine elevation capability through sound and music and hearing with live or recorded music, and is novel to an ageing population that has lost this experience. While particularly useful to ageing populations, especially in conjunction with cognitive associations, the methods are not limited to those populations.
In yet another embodiment, the system provides senior-specific licensed music content. In one embodiment, this music is selected to avoid references to unhappiness, ageing, and similar topics. Instrumental music is played at meal times so the Cocktail Party Effect is not exacerbated by words in vocal music content.
In yet a further embodiment, acoustic absorbing panels may be installed in individual resident's rooms, with or without loop antennas concealed inside. A small, rechargeable portable loop amplifier with microphone may also be provided to individuals, which can be used at dining room tables, similar areas, or in private rooms. For example, when used in a private room, an internal or external microphone can be used for communication with staff, family or friends. A digital or analog input can provide connection to TV, computer, Wi-Fi, Airplay, or the like.
In one embodiment, the acoustic panels may be printed with fabric that color coordinates with wall colors or room décor, or may be printed with photographs, art, scenes, or other images. They can be configured as tiles. In one example, multiple panels can appear as a view of a beach or mountain landscape from a large window. In another embodiment, the panels may be video panels or a video wall with similar imagery.
Over 66% of people over the age of 70 experience hearing loss, and this number increases with age (e.g., 75% of people over the age of 75). Hearing aids and similar devices, however, do not function well in senior assisted-living communities or facilities. White noise and background noise are not handled well by these devices, and lead to a reduction in social interaction. The loss of social interaction, and concomitant isolation and loneliness, results in more frequent illness, medical treatment, accidents, hospitalizations, and depression, which can lead to or exacerbate Alzheimer's disease, dementia and an overall failure to thrive.
In various exemplary embodiments, the present system is designed to improve the “acoustic wellness” of various public and private spaces, particularly in assisted-living communities or facilities, although the techniques and processes described below can be used in other areas or facilities, such as facilities or locations providing hospice care, hospice centers, nursing homes, hospitals, and residences.
