4 SOUND-INSULATING SLEEP PLLOW RELATED APPLICATIONS 0001 NOT APPLICABLE. FIELD OF THE INVENTION 0002 The present invention relates to pillows for sleeping. BACKGROUND OF THE INVENTION The following discussion is provided solely to assist the understanding of the reader, and does not constitute an admission that any of the information discussed or references cited constitute prior art to the present invention Historically, a conventional pillow supports and cushions a sleeper's head thereby providing comfort but pro vides little or no noise or light abatement. The poor sound deadening properties are due to a combination of selection of materials that are not efficient Sound deadeners, and configu ration that does not lend itself to efficiently covering the user's CaS Typically, when it is desirable to reduce noise levels, ear plugs are used. However, for many individuals, earplugs are annoying to use and also readily become soiled and/or lost. Likewise. Some individuals use eye masks to reduce light exposure Redewill, U.S. Pat. No. 5,313,678, entitled Acous tical Pillow, concerns a pillow that uses a spring inside of a U-shaped core to bias the end of the core against a user's ears, which is said to attenuate environmental Sound. SUMMARY OF THE INVENTION The present invention concerns a sleep pillow that is designed to improve sleep by reducing noise experienced by the user. The reduction in noise is accomplished using a cushion, e.g., a foam cushion, that wraps around the back and sides of a user's head, covering the ears. Additionally, the wrap-around pillows provide thermal insulation during cold conditions. In some advantageous embodiments, the pillow also includes an eye covering to block light, assisting a person to obtain restful sleep even when there is significant ambient light. Due to the preferred configuration of the cushion in a three section design, the pillow allows for both closed (wrapped around a person's head) and open (the unit lying flat) use For napping or sleeping, this invention also prefer ably includes built-in earmuffs in order to further reduce noise exposure. In a three section design, the two side pillows can each incorporate standard or electronic earmuffs. The standard earmuffs attenuate external noise, while the choice of electronic earmuffs are for those that prefer to rest with music or pre-taped ocean or similar relaxing Sounds Thus, in a first aspect the invention provides a sleep pillow that includes a central, back section, a left section, and a right section. Each of those sections includes a compliant foam filler and a fabric cover, where the left section and the right section are joined with the central back section, and where the pillow wraps around a user's head and holds itself in position In particular embodiments, the pillow also includes a closure that holds the left section and right sections over the ears of a user and holds the pillow in position; the closure includes a strap that passes over the face of a user (usually over the user's forehead), thereby holding the pillow in a U-shaped configuration; the strap also includes hook and loop fasteners (e.g., VELCROR); the strap also includes a release tab, where pulling on the release tab releases the strap, e.g., releases the hook and loop fasteners In certain embodiments, the left section and right section are hingedly attached on opposing sides of the central or rear section; the pillow will also lay flat on a bed surface, thereby allowing use of the pillow as a conventional pillow: the pillow also includes an eye cover (e.g., an eye mask); the eye cover is attached to the strap that holds the left section and the right section over the ears of a user Also in particular embodiments, the pillow also includes ear coverings in each of the left section and the right section; the ear coverings include depressions, thereby reduc ing pressure on a user's ears; the ear coverings are or include earmuffs; the ear coverings include earphones; the earphones are functionally connected with noise canceling circuitry; the earphones are functionally connected with timed alarm cir cuitry; the earphones are functionally connected with audio input, e.g., white noise, pink noise, music, radio, mp3 or other digital audio format, or the like In certain embodiments, the strap passes through recessed strap passageways or channels in the left section and right pillow sections; the pillow also include a removable and replaceable interior liner, e.g., attached with hook and loop fasteners In a related aspect, the invention provides a method for reducing noise disturbances during sleep for a user by fastening a pillow of the preceding aspect around a user's head in preparation for and during sleep In certain embodiments the method also includes covering the user's eyes with an attachedeye mask; the person is in a lighted environment; the person in on an airplane; the person is in a hotel; the pillow is used during daytime hours Likewise, in another related aspect, the invention provides a method for making an acoustical pillow of the first aspect above, wherein the method includes inserting three foam sections in separate pockets in a fabric covering forming three pillow sections, where the separate pockets are proxi mal to each other and the fabric covering provides hinge connections between the pillow sections In particular embodiments, the method also involves adding further features described for embodiments of the first aspect above, such as installing an adjustment strap, installing ear coverings (which may involve cutting recesses in a respective foam sections), installing an eye mask in the adjustment strap, installing a liner and/or fasteners for a liner on the inner Surface of the pillow, e.g., on the inner Surface of the pillow covering, as well as other Such steps Additional embodiments will be apparent from the Detailed Description and from the claims. BRIEF DESCRIPTION OF THE DRAWINGS (0019 FIG. 1 is a front view of the invention open with no liner shown. The three separate pillows are connected with a sleeve of a fabric material allowing for both open and closed use of the invention. An opening in each side pillow allows for a person's ear to fit into built-in earmuffs. Velcro strips are used to attach the washable liner FIG. 2 depicts the invention open at top view. The adjustment strap is shown with it's attachment to the rear pillow, then extending forward through a fabric material loop. In this figure the liner is shown.

5 0021 FIG.3 shows a side view. The side pillows are both shaped with an indentation so as to prevent the earmuff from contacting the sleeping Surface, thus preventing excessive pressure against the person's ear caused by the person's head weight FIG. 4 depicts a person sleeping on his/her side with the pillows closed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 0023 The present invention provides a pillow that assists individuals to have restful sleep even under conditions where environmental noise would otherwise be a problem. In addi tion, the present pillow can be fitted with an eye mask which further assists the user to achieve restful sleep under difficult conditions. Thus, the pillow is particularly advantageous for individuals who work during the night and therefore must sleep during the day and/or for travelers who must sleep in noisy and/or light-filled environments Thus, in general, the pillow includes a padding material that acts as an acoustic barrier and is configured Such that the pillow wraps around the back and sides of a user's head, thereby covering the person's ears and the adjacent portions of the person's head. Typically, the pillow segments are held in place around the person's head with a strap that is fastened to or wraps around at least the side pillow sections and passes across the persons face (usually across the per son's forehead). In this way, the pillow provides both conven tional pillow support for a sleeper in a back or side sleeping position, and reduces perceived noise levels. As indicated above, advantageously the pillow can also include an eye mask, which is usually attached to the strap that holds the pillow sections in place around the person's head Segmented Pillow: Thus, in particular advantageous embodiments, the pillow has three connected pillow sections, which may be generally rectangular sections. These pillow segments are typically constructed of a foam filler (memory or conventional foam), which is usually covered in a fabric material. As indicated above, during use, the three segments wrap around the user's head such that the central pillow segment is at the back of the user's head and the two side pillow segments are at the sides of the user's head, covering the user's ears. In many cases, the pillow sections have Sub stantially parallel inner and outer Surfaces, such that each pillow section provides stable positioning in any of three sleep positions (i.e., with the person resting on their back or on either side) Because it is desirable to protect the pillow padding from Soiling, tearing, and other damage, preferably the pillow sections are covered. For example, each pillow section can be covered with a fabric or breathable film. That covering can also provide the connection between the sections. The cover ing can be constructed as a removable sleeve. Any of a large number of different fabrics and films may be used, including, for example, fabrics made of natural fibers such as cotton and wool, synthetic fibers such as polypropylene or polyesters, and mixtures of natural and synthetic fibers. As indicated, breathable film materials and materials that include breath able films may also be used, e.g., GORE-TEXR and similar materials The covering will also usually provide the physical connection between pillow segments. While the pillow sec tions can be connected Such that the pillow is naturally in a U-shaped configuration, in most cases the connections between the pillow sections will also constitute a hinge. In this way, the pillow can be laid flat on a sleep Surface and used as a conventional flat pillow, or can be wrapped around the person's head as described above. Where the covering pro vides such hinging, generally the individual pillow sections will fit into separate pockets or chambers in the covering Generally, the two side pillow sections are thicker than the rear or middle pillow segment. This difference in thickness allows the pillow to Support the person's head in a comfortable positions (preferably with proper spinal align ment) when a person rests on his/her side. Similarly, the rear pillow is thinner in thickness for comfort requirements when a person is resting on his/herback. The cross-sectional area of the pillows may vary but in general are sized to accommodate typical head size. Thus, for example, the rear section typically will have a width that is approximately the same as the aver age width of peoples heads In advantageous embodiments, the side sections of the pillow are relieved such that the pressure against the person's ears due to the weight of the person's head is reduced. This can be accomplished in various ways, e.g., by indenting the inner Surface over the ear area and/or by indent ing the outer surface such that the thickness of the pillow section over the ear area is reduced. For example, the outer Surface can be indented by providing a U-channel for the strap to pass through, e.g., a channel about 1-5 cm or even more in depth. The depth of the channel can be varied depending on the thickness of the pillow section and the degree of thickness reduction desired Liner: In addition to the covering, the pillow can also advantageously include a liner, preferably a removable liner. Such a liner can be designed such that it is readily removable and replaceable, e.g., using hook and loop fasten ers such as VELCROR) fasteners. Thus, the liner can be removed and replaced with a new liner, or can be cleaned and then placed back on the pillow. The liner material is prefer ably selected to be comfortable for contact with a person's skin, and/or readily cleanable, such as by washing (preferably by machine washing) Strap: As described above, the pillow is typically held around a person's head using a strap or straps. Usually the strap is made of conventional synthetic fiber webbing. In most cases, the strap(s) is connected with the covering Such that the strap passes around the front of the user's head, e.g., across the person's forehead. The strap is adjustable, e.g., using hook and loop fastener(s). In certain embodiments, the adjustment strap (e.g., one or two separate pieces) is attached at the rear or central pillow and extends forward on both sides and is secured with VELCROR) at a front location Ear Muffs: Both side pillows can advantageously incorporate built-in earmuffs (passive or electronic). Such ear muffs assistin sealing against or around the person's ears. The pillow section (e.g., the foam itself) is shaped or molded to accommodate the installation of earmuffs. Typically, the design incorporates an opening in the liner (if present) and pillow covering material for each ear to rest within the respec tive earmuff. When electronic earmuffs (i.e., headphones) are used, the earmuffs can be driven by electronics in or attached to the pillow, or may be separate (e.g., with wired or wireless connections) The electronics may be noise-canceling and/or can provide audio Such as white noise, pink noise, or selected audio Such as music. Where audio is provided, the audio may be timed (e.g., turns off after a period of time) or can be continuous.
