Abstract: A communication device (1, 15, 25, 35) comprising a housing (2) with a housing wall (50) bounding a space (7). The housing (2) comprises a first housing part (3) and a second housing part (4), which are joined along a dividing line (40), whereby a first abutment face (41) of the first housing part (3) abuts a second abutment face (42) of the second housing part (4) along the dividing line (40). A first microphone transducer (8) is arranged in the housing (2). The first microphone transducer (8) comprises a microphone opening (9), which is connected to the space (7). The space (7) is communicating with the surroundings via a peripheral line (47) of housing openings (39) in the outer side (44) of the housing wall (50) arranged along the dividing line (40), and housing channels (46) extending between the housing openings (39) and the inner side (43) of the housing wall (50). The housing channels (46) and the housing openings (39) are provided as recessions (45; 48) in the first abutment face (41). The invention also relates to the manufacturing such a communication device.

Abstract: The present invention relates to a method and a system for estimating acoustic noise levels. The invention may advantageously be applied in systems comprising multiple audio communication devices, such as e.g. telephones, mobile phones, headsets and headset base stations.It is an object of the present invention to provide respectively a method for estimating acoustic noise levels and a system for estimating acoustic noise levels, which enable a more efficient use of resources and may reduce cluttering in offices and other working environments than the prior art.This and other objects are achieved by a method for estimating acoustic noise levels, the method comprising: (66) for each of two or more audio communication devices (1, 21, 31), receiving an acoustic signal (61) from ambient space (62) and providing a corresponding microphone output signal (63) by a microphone (5, 7, 23) comprised by the respective audio communication device (1, 21, 31) and (67) repeatedly estimating a local acoustic noise level (64) in dependence on the microphone output signal (63); and (68) repeatedly estimating a location-dependent distribution of acoustic noise levels in ambient space (65) in dependence on the local acoustic noise levels (64).
