Definitions
- THIS INVENTION relates to roads. More particularly it relates to a method of generating sound. It also relates to a method of arranging rumble strips and to an arrangement of irregularities on a road. It further relates to a road, to a portable sound generating arrangement and to an installation.
- a method of generating sound which includes providing on a road a sound generating arrangement configured such that a vehicle wheel driving over the sound generating arrangement generates a predetermined sequence of sounds.
- the method may include providing irregularities on the road configured to generate the predetermined sequence of sounds.
- the irregularities may be in the form of ribs or ridges which extend transversely relative to the intended direction of travel of a said vehicle wheel and which are longitudinally spaced apart.
- the irregularities may be in the form of depressions, grooves, embedded features, or the like.
- the method may include the step of arranging the irregularities in longitudinally spaced sets, the irregularities in each set being configured so that the sounds generated by the sets have a desired relative frequency and duration.
- the sequence of sounds generated is in the form of a melody, e.g. an advertising jingle.
- the method may include arranging the irregularities in two transversely spaced groups, each group comprising a plurality of longitudinally spaced irregularities positioned such that the wheels on the left hand side of a vehicle travelling along the road pass over the one group of irregularities and the wheels on the right hand side of the vehicle pass over the other group of irregularities.
- the method may include providing the irregularities as an integral part of a surface of the road, e.g. in the form of rumble strips.
- the method may include securing the irregularities on the road so that they are removable therefrom.
- the method may include the prior step of determining the desired arrangement of irregularities analytically.
- a method of arranging rumble strips on a road which includes arranging the rumble strips so that a vehicle wheel passing over the rumble strips generates a predetermined sequence of sounds.
- the method may include arranging the strips in longitudinally spaced apart sets, each set comprising a plurality of longitudinally spaced apart strips configured so that the sounds generated by the sets of rumble strips have a desired relative frequency and duration.
- the method may include arranging the rumble strips in two transversely spaced groups each group comprising a plurality of longitudinally spaced apart rumble strips positioned such that the wheels on the left hand side of a vehicle travelling along the road pass over the one group of rumble strips and the wheels on the right hand side of the vehicle pass over the other group of rumble strips.
- the spacing between strips in the sets may differ to provide a stereo effect.
- the strips over which a left wheel of the vehicle passes may be about 20 mm apart and the strips over which a right wheel of the vehicle passes may be about 1 5 mm apart.
- Different sounds may be achieved by varying the spacing between the rumble strips and/or varying the material and/or other physical characteristics, e.g. shape and/or size, of the rumble strips.
- the sequence of sounds may be in the form of a melody, e.g. an advertising jingle.
- the method may include the prior step of determining the desired arrangement of rumble strips analytically.

- the irregularities may be arranged in longitudinally spaced apart sets.
- the spacing between the irregularities in at least two of the sets of irregularities may differ.
- the number of irregularities in at least two sets of irregularities may differ.
- Each set may comprise a plurality of longitudinally spaced apart irregularities configured so that the sounds generated by the sets of irregularities have a desired relative frequency and duration.
- the arrangement of irregularities may include two transversely spaced groups of irregularities, each group comprising a plurality of longitudinally spaced irregularities.
- the sequence of sounds may be in the form of a melody.
- a road having a road surface configured such that a vehicle wheel driving over the road surface generates a predetermined sequence of sound.
- the road surface may include a plurality of irregularities configured to generate the predetermined sequence of sound.
- the irregularities may be in the form of ribs or ridges which extend transversely relative to the intended direction of travel of a said vehicle wheel and which are longitudinally spaced apart.
- a road which includes an arrangement of irregularities of the type described above provided thereon.
- the ridges may be fast with the road.
- the ridges may be removable.
- the ridges may be of metal. Naturally, other materials can be used to optimise the tonal quality of the sound which is generated.
- a portable sound generating arrangement which is transportable to and can be positioned on a road at a desired location and is configured to generate a predetermined sequence of sounds when a vehicle wheel is driven over the arrangement.
- the arrangement may include a plurality of interconnected sound generating elements and securing means for securing the arrangement in position on a road with the sound generating elements at a predetermined spacing.
- the arrangement may be elongate and the sound generating elements may be in the form of longitudinally spaced transversely extending elongate elements which are connected together by connection means.
- an installation which includes a sound generating arrangement provided on a road and configured such that a vehicle wheel driving over the sound generating arrangement generates a predetermined sequence of sounds; and a visual display which is positioned relative to the sound generating arrangement so that matter displayed thereon is visible to an occupant of a said vehicle at the same time as the predetermined sequence of sounds is generated.
- the sound generating arrangement may include a plurality of irregularities provided on the road.
- the irregularities may be defined by a surface of strips on the road surface.
- the arrangement of irregularities may be formed by a portable sound generating arrangement which is secured on the road.
- the information presented on the visual display may relate to advertising, e.g. of products or services, the sequence of sounds being a melody associated with the advertising.
- the visual display may be a billboard.
- Figure 1 shows a plan view of part of a road in accordance with the invention
- Figure 2 shows, on an enlarged scale, a longitudinal sectional elevation of part of the road in accordance with the invention
- Figure 3 shows another embodiment of a the road in accordance with the invention
- Figure 4 shows a plan view of a portable sound generating arrangement in accordance with the invention, the arrangement being secured to a road;
- Figure 5 shows a three-dimensional view of an installation in accordance with the invention.
- reference numeral 1 0 generally indicates a road in accordance with the invention.
- the road 1 0 has a surface 1 2 along which a vehicle is intended to drive in the direction of arrow 14.
- the road 10 includes a plurality of irregularities in the form of ribs or ridges 1 6, which extend transversely across the surface 1 2 and which are longitudinally spaced apart relative to the arrow 14.
- the ridges 1 6 are arranged in a plurality of longitudinally spaced apart sets 1 8.
- Each set 18 comprises a plurality of longitudinally spaced apart ridges 1 6 configured such that when a vehicle wheel passes over the ridges 1 6 in a set 1 8 at a predetermined speed, a predetermined sound is generated.
- the Inventor believes that for a given vehicle speed the frequency and hence the pitch of the sound generated will be inversely proportional to the spacing between the strips.
- the duration of a sound will be determined by the total length of a set 1 8 in the direction of travel of the vehicle, coupled with the vehicle speed.
- 1 6 were formed by securing pine strips having a width W of approximately 51 mm (2 inches) in position on a road surface. Tests were conducted with thirty strips secured to the road surface and spaced apart 20 cm.
- the Inventor then calculated the desired spacing as well as the number of ridges 1 6 which will be required in a set to produce a note of a particular frequency and duration. This was done for a predetermined sequence of notes and the ridges 1 6 were then arranged in sets 1 8 which were spaced apart at desired intervals corresponding to the spacing between the predetermined notes, the spacing of the ridges 1 6 in each set 1 8 and the number of ridges 1 6 corresponding to the desired note and duration thereof. The Inventor then found that by driving a vehicle over the road surface 1 2 on which the ridges 1 6 were mounted a predetermined sequence of sounds were generated. In particular, the Inventor generated a melody in the form of an advertising jingle.
- the Inventor believes that it may be preferable to position the ridges 1 6 at a location on the road where the speed of travel of any vehicles using the road is fairly predictable. Nevertheless, the predetermined arrangement of the ridges 1 6 ensures that the sounds generated by the sets of ridges have a fixed relative frequency and duration, regardless of the speed of the vehicle thereby permitting a known melody, e.g. an advertising jingle, to be recognised even if the key is different to the usual key of the melody.
- a known melody e.g. an advertising jingle
- the material and configuration of the ridges 1 6 can vary as desired. Hence, they could be of wood or metal as mentioned above. Instead, they may be in the form of rumble strips which are integral with the road.
- Figure 3 of the drawings shows a further embodiment of a road 1 00 in accordance with the invention, with like reference numerals referring to like parts.
- the ridges 1 6 are not only arranged in longitudinally spaced apart sets, but also in two transversely spaced groups 1 8.2, 1 8.4.
- a left wheel of the vehicle travels over one of the groups 1 8.4 and a right wheel travels over the other group 1 8.2.
- An occupant of the vehicle will experience the sounds generated by the respective wheels travelling over their associated groups of ridges as coming from different sides of the vehicle, thereby creating a stereo effect.
- the spacing between the ridges 1 6 of two transversely spaced sets (e.g. 1 8.2 and 1 8.4) differs, the pitch of the sound generated by the left wheel of the vehicle will differ from the pitch of the sound generated by the right wheel of the vehicle.
- the spacing between the ridges 16 can be arranged such that these sounds are in harmony.
- the ridges 1 6 of two transversely spaced groups may be equally spaced, but the ridges of one set 1 8.8 may slightly lag the ridges 1 6 of its corresponding set 1 8.9. In use, this produces a slight delay between the sounds generated by the left and right wheels of the vehicle respectively, enhancing the stereo effect.
- the irregularities can be defined by a portable sound generating arrangement 1 10 ( Figure 4) .
- the sound generating arrangement 1 1 0 includes a plurality of steel bars 1 1 6 arranged in a plurality of sets 1 1 8, the bars being interconnected by connection means in the form of two transversely spaced chains 1 20.
- the arrangement 1 1 0 also includes securing means in the form of nails 1 30 which can be driven into a road 1 1 1 , each nail 1 30 being shaped and dimensioned such that a shank of the nail 1 30 can pass through a link of the chain 1 20.
- the sound generating arrangement 1 1 0 is secured to the road 1 1 1 by positioning the arrangement 1 10 on the road surface
- the bars 1 1 6 of the arrangement 1 1 0 form an arrangement of irregularities on the road surface such that a predetermined sequence of sounds is generated when a vehicle wheel passes over the arrangement 1 10.
- the sound generating arrangement can be transported to a desired location and secured in position where the predetermined sequence of sounds is generated.
- reference numeral 210 generally indicates an installation in accordance with the invention.
- the installation 210 includes a visual display in the form of an advertising billboard 220, which presents information 222 in the form of an advertisement, e.g. for a particular product.
- the arrangement 210 also includes an arrangement of irregularities on a surface 21 2 of a road 21 1 in the form of transversely extending ridges 21 6.
- the ridges 21 6 are arranged in longitudinally spaced apart sets 21 8 so that a predetermined sequence of sounds is generated when a vehicle wheel is driven over the sets 21 8.
- the predetermined sequence of sounds is an advertising jingle which can be associated with the advertised product or with a company that sells the product.
- a road surface or device in accordance with the invention will be capable of generating a range of sounds which can be arranged in a predetermined sequence, typically in the form of an advertising jingle, which will provide organisations with additional scope to advertise their product.
