Definitions

the present invention relates to a cerumen protection device for a hearing aid or other hearing device, for.
a headset with a carrier having a sound passage opening, and a membrane which is stretched over the sound passage opening to protect against penetrating cerumen.
Hearing aids are exposed to various substances in daily use, which can cause soiling in the devices and especially in the transducers of the devices. Such substances are especially sweat and cerumen. Dirt within the transducers, namely the microphones and handsets, leads to high service costs, since the dirty transducers must be cleaned and in the worst case, even replaced.
open wax protection systems are often used, so that the cerumen can not easily reach the listener, for example.
open cerumen protection systems can not always prevent the contamination of the listener.
the protective membranes are very thin for acoustic reasons, they are also very susceptible to damage and destruction. Therefore, it must be constantly checked if the Membrane is still intact. In this case, however, there is the problem that the sound opening, over which the membrane is stretched, is usually very small, so that damage to the membrane can be perceived optically only with difficulty.
the object of the present invention is therefore to propose a cerumen protection device in which the damage of a membrane can be more easily detected.
this object is achieved by a cerumen protection device for a hearing aid with a carrier having a sound passage opening, and a membrane that is stretched over the sound passage opening to protect against penetrating cerumen, wherein the brightness contrast between the membrane and the support greater than 0.1 is.
the invention there is a clearly perceptible contrast between the protective membrane for the eye and the wearer so that when the membrane ruptures, the underlying wearer becomes visible and thus damage can easily be detected.
the brightness contrast between the membrane and the support is greater than 0.3, greater than 0.5, greater than 0.7 or even greater than 0.9.
the stronger the contrast between the two components the easier it is to detect damage to the membrane.
the acoustic detection of a defect of the membrane is much easier than with the commonly used transparent membranes.
the color contrast between the membrane and the carrier it may be helpful if the color of the membrane is at least 90 ° apart from the color of the carrier on the color wheel. It is even better if the two colors are essentially complementary. As a result, even in poor lighting conditions, there is usually a good opportunity to examine the membrane reliably.
the support on which the membrane is mounted may be funnel-shaped.
the carrier in the case of a crack behind a large part of the membrane, the carrier can be perceived optically.
the wax protection device shown schematically in FIG. 1 has a substantially funnel-shaped support 1. With its tapered end 2 of the carrier is plugged into a sound outlet of a receiver, not shown, a hearing aid. At its opposite end, the carrier 1 has a wide sound opening 3, which is spanned by a membrane 4.
the membrane 4 has, for example, a dark color, while the membrane support 1 is lightly colored. Due to this clear bright-dark contrast, a defect of the membrane 4 can be easily recognized, since the light carrier 1 becomes visible through the damaged, dark membrane 4.
the brightness difference between the membrane 4 and the carrier 1 determines the brightness contrast between the two components.
I max denotes the light intensity of the lighter and I min the light intensity of the darker component.
the luminous intensity itself represents the quotient of luminous flux and solid angle.
the term "brightness contrast" used in this document refers to the above definition.
L indicates whether the luminance of an object and L.sub.U the luminance of the environment.
the physiological contrast K ph can assume values between -1 and + ⁇ .
the brightness contrast values specified above and in the claims can be converted into corresponding physiological contrast values.
the core of the invention, that between the carrier and membrane is to consist of increased contrast remains unaffected.
the brightness contrast just described can be considered as a physical contrast variant.
the human eye is also able to perceive other optical contrasts.
contrast definitions in addition to the light-dark contrast such as: cold-warm contrast, color-to-itself contrast, complementary contrast, quality contrast, quantity contrast, simultaneous contrast and successive contrast.
the essence of the present invention is to set a good perceivable contrast between the support and the membrane.
the color contrast is used to better perceive a defect of the membrane.
the blue-yellow-red color circle of the painting illustrated in FIG. 2 is used.
the three main colors blue, red and yellow lie on the color wheel at a distance of 120 °.
the two colors used should be at least 60 ° apart. In FIG. 2, this is indicated for dark and light orange. At a distance of at least 90 °, the color contrast is already significantly higher, for example for dark organs and yellow. If the colors used for the membrane 4 and the support 1 are directly opposite each other on the color wheel, the two colors are complementary to one another and the greatest color contrast is achieved (in the example chosen: dark organ and turquoise). A defect of the membrane 4 can then be easily recognized by color.
