1. A panel for ventilation and both reactive and dissipative sound dampening which comprises: a) a front, a back, a top, a bottom, a right side and a left side defining a hollow centre there between;b) at least one vertically oriented ventilation groove on the front of the panel (front groove) for passive air passage to the hollow centre and at least one vertically oriented ventilation groove on the back of the panel (back groove) for passive air passage to the hollow centre, wherein the front groove and the back groove are non-linear, staggered and form a Z-shaped air channel within the hollow centre;c) a plurality of horizontally dispersed, staggered baffles in the hollow centre; andd) a plurality of at least partial resonators on the periphery of the hollow centre. 2. The panel of claim 1 which forms part of at least one of a door, a wall, a window and a partition. 3. The panel of claim 1 wherein the at least partial resonators are on right and left side of the panel. 4. The panel of claim 1 wherein the at least partial resonators are made whole by engagement of the panel with a stile, said stile comprising a remaining portion of the resonators. 5. The panel of claim 1 comprising necks of the resonators on the periphery of the hollow centre, said necks being mate-able with cavities of the resonators disposed within a stile, when said panel and stile are operably engaged. 6. The panel of claim 1 comprising necks of the resonators on the periphery of the hollow centre, said necks being mate-able with cavities of the resonators disposed within a stile, when said panel and stile are operably engaged, thereby forming a Helmholtz resonator, comprising a neck, a cavity and an opening. 7. The panel of claim 1 wherein the at least partial resonators are at least partially filled with sound absorptive material. 8. The panel of claim 1 wherein the at least partial resonators are necks having openings which face the vertically oriented ventilation grooves. 9. The panel of claim 1 wherein the baffles comprise sound absorbing material. 10. The panel of claim 1 wherein the baffles are comprised of at least one of acoustic tiles, fibreglass and acoustical foam. 11. At least one of a door, a wall, a partition and a window comprising at least one panel of claim 1. 12. A door comprising at least one panel of claim 1 set between at least two stiles and at least two rails. 13. A flush door comprising at least one panel of claim 1 set between at least two stiles and at least two rails covered with, at front and back, veneers. 14. A panel system comprising: a) at least one panel, said panel comprising: a front, a back, a top, a bottom, a right side and a left side defining a hollow centre there between; at least one vertically oriented ventilation groove on the front of the panel (front groove) for passive air passage to the hollow centre and at least one vertically oriented ventilation groove on the back of the panel (back groove) for passive air passage to the hollow centre, wherein the front groove and the back groove are non-linear and staggered and form a Z-shaped air channel within the hollow centre; a plurality of horizontally dispersed, staggered baffles in the hollow centre; and a plurality resonator necks on the periphery of the hollow centre;b) a rail disposed between every two panels; andc) at least two stiles comprising resonator cavities, said stiles and cavities defining a groove into which resonator necks are mated, to secure panel and stile together. 15. A panel structure for ventilation and both reactive and dissipative sound dampening which comprises a frame disposed between a front surface and a back surface, wherein frame comprises at least two rails and two stiles and a slotted muntin and wherein said frame is disposed between the front surface and the back surface to form a hollow cavity defining in part a Z-shaped airflow pathway, from at least one vertically oriented ventilation groove on the front surface (front groove) for passive air passage to the hollow cavity and at least one vertically oriented ventilation groove on the back surface (back groove) for passive air passage to the hollow cavity, wherein the front groove and the back groove are non-linear and staggered and wherein at a right side and left side of the cavity, through a plurality of slots in the muntin, there are a plurality of resonators; and wherein, pressed between the front surface and the back surface are situate a plurality of staggered horizontally oriented baffles. 16. The panel of claim 15 wherein the baffles comprise sound absorbing material. 17. The panel of claim 15 wherein the baffles are comprised of at least one of acoustic tiles, fibreglass and acoustical foam. 18. At least one of a door, a wall, a partition and a window comprising at least one panel structure of claim 15. 19. The panel of claim 15 wherein foam fills a cavity between slotted muntin and stile.
