- FIG. 2 is a diagram showing the steps of a presence simulation method according to one embodiment of the invention.
- FIG. 1 schematically represents a device for processing and broadcasting sounds according to one embodiment of the invention.
- This device comprises a housing 1, in which are contained various electronic components.
- this housing 1 is made of thermoplastic elastomer and has a heart shape.
- This housing 1 may however, in other embodiments, have different shapes, and be made of any suitable material known to those skilled in the art.
- this housing 1 is shown open, so as to show the components it contains.
- the sound processing and diffusion device comprises a cover 2 made of textile material, surrounding the housing 1. This cover 2 is advantageously removable, and can be removed from the sound processing and distribution device.
- This housing 1 notably contains at least one battery 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-emitting diode 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 sound processing and diffusion 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 battery charging functionality implemented in particular by the microcontroller 51, the power socket 55 and the batteries 3.
- the microcontroller 51 advantageously makes it possible to assign the device for processing and broadcasting sounds to one or other of the functions indicated above. Preferably, these functionalities are not implemented simultaneously. [043] The microcontroller 51 makes it possible to place the device for processing and broadcasting sounds in different distinct states. Among these states:
- the microcontroller 51 is capable of detecting the connection of an electrical power supply to the power supply socket 55. In this case, it places the sound processing and distribution device in the state of charging the batteries 3. , by interrupting, if necessary, the recording state or the sound broadcasting state. Such an interruption of the sound broadcasting and recording functionalities, when the sound processing and broadcasting device is connected to an electrical supply, advantageously makes it possible to avoid any risk of accident of electrical origin.
- the recording functionality of the sound processing and broadcasting device is enabled.
- This recording functionality is implemented by the electronic components which have the functionality of recording the surrounding sounds and of processing 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, functioning for example on the microcontroller 51. [047] According to a preferred embodiment, when the microcontroller 51 activates the recording functionality, 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 having recorded sounds, the sound processing component 52 performs several specific treatments 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 highest frequencies. This processing may consist of frequency filtering intended to greatly limit the highest frequencies. Thus, 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 sharp burst of voice, which could stress the newborn and / or impair 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 sound processing and distribution device 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 sound processing and broadcasting device, as part 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 recording of sound imitating the perception of the heartbeats can be modulated, from information linked to the weak signal representative of the heart rate of the reference person, which was captured previously. by the recording functionality.
- the sound processing and distribution device can mix these sound tracks, or broadcasts one or the other, according to 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 new 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 sequence is favorable to the gradual appeasement of the newborn.
- the total duration of the sound sequences broadcast by the method using the device according to the invention is preferably between 12 to 25 minutes, preferably 12 minutes. Another preferred duration is 20 minutes, but all times are possible with the method and device according to the invention, although these do not exceed or equal 25 minutes in order to obtain the technical results and effects sought by the manufacturers. inventors.
- the method and the device according to the invention thus make it possible to broadcast simultaneously or not a sound track comprising the sound of the voice of the person whose presence is to be simulated, accompanied or not by a sound track of heartbeats, accompanied or not by a sound track comprising music, then a sound track comprising music, such as a lullaby, whispers, hums, musical instruments, animal sounds, everything that a person skilled in the art knows and would use to appease or simulate the presence of a reference person, and a sound track corresponding to the heart alone, or to the voice of the reference person alone.
- the music can be played over all the periods but preferably in the second period of the sound sequence.
- the device is equipped with a light emitting diode 54, which can give indications to the user using the device for processing and broadcasting sounds.
- This diode can in particular, for example by its flashing or its color, indicate the state in which the device is located, the state of charge of its battery, etc.
- this light-emitting diode can also participate in the simulation by diffusing, continuously or variably, a light of low intensity, in a range of wavelength chosen to calm the patient. new born.
- the components of the sound processing and diffusion device are chosen so as not to emit electromagnetic waves at frequencies or at intensities liable to disturb neighboring electronic equipment.
- the device for processing and broadcasting sounds in a hospital context, near medical electronic equipment, in fact prohibits any risk of disturbance of this medical equipment.
- the device for processing and broadcasting sounds according to the embodiment shown in particular does not include any radio communication interface.
- the limitation of the emissions of electromagnetic waves makes it possible to prevent the newborn placed in the vicinity of the device for processing and broadcasting sounds from receiving such waves, and therefore to eliminate any risk of such waves have a detrimental impact on his health.
- the device for processing and broadcasting sounds is designed so as to be compatible with use in a medical or hospital environment.
- the materials used for the manufacture of the device, and the shapes of this device are chosen so as to meet the hygiene requirements necessary in such environments.
- FIG. 2 schematically represents the steps of a method of broadcasting sound intended for newborns.
- This method comprises a step 61 of recording a voice, more precisely the voice of the reference person.
- This recording step 61 is followed by two sound processing steps.
- a first sound processing step 62 consists in adjusting the volume of the recording so that its maximum volume does not exceed a determined value.
- a second sound processing step 63 of reducing the high frequencies, consists in reducing or eliminating, on this recording, the sound components whose frequency is higher than a determined frequency, in the spectrum of audible frequencies.
- These two sound processing steps 62 and 63 can be carried out simultaneously or successively. If they are carried out successively, the first sound processing step 62 can equally well be carried out before or after the second sound processing step 63.
- this method comprises a sound broadcasting step 64, during which the recording previously made and processed is broadcast, preferably mixed with another recording comprising a low frequency sound imitating the perception of the beating of the heart.
