- the devices and methods according to the invention are both suitable for newborns, and premature newborns, and children whose terms are used in an equivalent and substitutable manner in the present application.
- FIG. 1 schematically represents a device for generating sensory stimuli according to one embodiment of the invention.
- This device comprises a housing 1, in which the various electronic components are contained.
- This housing 1 notably contains batteries 3, a loudspeaker 4 and an electronic card 5, connected together.
- the electronic card 5 notably carries a microcontroller 51, a sound processing component 52, a microphone 53, a light source 54, a power socket 55 and a control button 56.
- the microcontroller 51 notably ensures the control of all the other components, so that the device can implement several functionalities, among which the following functionalities:
- a recording functionality implemented in particular by the microcontroller 51, the sound processing component 52 and the microphone 53,
- a sound diffusion functionality implemented in particular by the microcontroller 51, the sound processing component 52 and the loudspeaker 4,
- a light diffusion functionality implemented in particular by the microcontroller 51 and the light-emitting diode 54,
- a battery charging functionality implemented in particular by the microcontroller 51, the power socket 55 and the batteries 3.
- the microcontroller advantageously makes it possible to assign the device according to the invention to one or other of the functionalities indicated above. Preferably, these functionalities are not implemented simultaneously. [075]
- the microcontroller makes it possible to place the device in different distinct states. Among these states: a recording state, in which the recording functionality allows the recording and processing of sounds, - a sound broadcasting state, during which the sound broadcasting functionality allows the broadcasting of sounds, which may include one or more previously recorded sound tracks, a battery charging state, in which the sound processing and distribution device is connected to a power source, and the battery charging functionality is active.
- the microcontroller 51 is capable of detecting the connection of an electric power supply to the power supply socket 55. In this case, it places the device according to the invention in the battery charging state, by interrupting, if necessary, the recording state, the sound diffusion state or the light diffusion state. Such an interruption of the sound diffusion, recording and light functions, when the device is connected to an electrical supply, advantageously makes it possible to avoid any risk of accident of electrical origin.
- the sound source or the sound means comprises several functionalities [079]
- the recording functionality of the sound processing and broadcasting device is activated.
- This recording functionality is implemented by the electronic components whose functionality is to record the surrounding sounds and to process the sounds with a view to their diffusion, and in particular the microphone 53 and the sound processing component 52.
- This sound processing component 52 can be an electronic component dedicated to sound processing. It can also be, in other embodiments, a software audio driver, running for example on the microcontroller 51.
- the microphone 53 records a sound, preferably a sound in which the voice of the reference person appears in a privileged manner.
- the recording functionality thus allows recordings from a few seconds to a few minutes.
- the reference person make this recording of his voice by placing the box 1 against his chest.
- the microphone 53 can thus pick up, in addition to the voice, a weak signal representative of the heart rate of the reference person.
- the sound processing component 52 After recording sounds, the sound processing component 52 performs several specific processing on these sounds.
- the sound processing component 52 performs processing of the recorded sounds to limit the maximum sound volume to a determined value.
- This processing may for example consist of reducing the volume of the entire recording, so that the entire recording has a volume lower than the predetermined value. It may also consist, in another embodiment, in a greater reduction in the recording volume of the recording portions having too high a volume. In this case, this limitation of the maximum sound volume results in a smoothing of the sound volume of the recording.
- the sound processing component 52 also performs, according to the invention, a processing of the recorded sounds to specifically reduce the volume of the sounds having the higher frequencies. This processing may consist of frequency filtering intended to greatly limit the highest frequencies. So in the In the embodiment shown, this processing is performed by a first order low pass filter with a cutoff frequency of 400 Hz, which attenuates frequencies above 400 Hz at a rate of 20 dB per decade.
- Such sound processing makes it possible, when the sound is subsequently broadcast near a newborn child, to greatly limit the impact, on the ears of the newborn, of high-pitched or strident sounds, such as a high-pitched voice, which could stress the newborn and / or degrade his hearing, particularly in the case of a premature newborn whose hearing functions are not fully formed.
- the sound broadcasting functionality of the sound processing and broadcasting device is activated. This sound broadcasting functionality is implemented in particular by the electronic components which have the function of broadcasting sounds, and in particular by the loudspeaker 4 and the sound processing component 52, under the control of the microcontroller 51.
- the sound processing component 52 can thus broadcast, via the loudspeaker 4, selected sounds.
- this sound diffusion functionality allows the device according to the invention to diffuse sounds originating from at least two distinct sound tracks. At least one of these tracks consists of a voice sound, which has been previously recorded and processed by the device according to the invention, within the framework of the recording functionality.
- another of these tracks consists of a recording of low frequency sound imitating the perception of heartbeats.
- This recording can, in an advantageous embodiment, have a rhythm and a sound volume, possibly variable over time, specifically chosen to obtain a soothing effect.
- the rhythm of this sound recording imitating the perception of heartbeats can be modulated, from information related to the weak signal representative of the heart rate of the reference person, which has previously picked up by the recording functionality.
- the device according to the invention can mix these sound tracks, or broadcasts one or the other, in functionality of a predefined sequence.
- the sound sequence that can be broadcast is as follows: for a period of eight minutes, a sound track comprising the sound of the voice of the person whose presence is to be simulated is accompanied by a heartbeat sound track. Then, for a further period of two minutes, the sound volume of the track including the sound of the voice gradually decreases, while the sound of heartbeats persists. Finally, during a final period of two minutes, only the sound of heartbeats is played.
- a sound track comprising the sound of the voice of the person whose presence is to be simulated is accompanied by a heartbeat sound track. Then, for a further period of two minutes, the sound volume of the track including the sound of the voice gradually decreases, while the sound of heartbeats persists. Finally, during a final period of two minutes, only the sound of heartbeats is played.
- Such a sound sequence is favorable to the gradual appeasement of the newborn.
- the inventors have produced sound sequences with a period of eight to ten minutes of a sound track comprising the sound of the voice of the person whose presence is to be simulated and accompanied by a sound track of heartbeats, a new period of eight to ten minutes with a sound track including music and for a final period of two minutes only the sound of heartbeats is played and gradually decreases.
