What is being done
to solve the problems
There
is no regular monitoring of the noise level in the streets, in
industrial, residential, and public buildings. The ministry of
Health does only regular spot
checks.
The
maximum allowable noise level established in Bishkek is 65
dBA.
On average the noise level above the maximum allowable limit in the
main thoroughfares of Bishkek was 8 dBA. Due to some city planning
decisions a part of sound-proofing plantations belts had been
destroyed and the noise level in residential houses (with windows
closed) was recorded to be 6 dBA higher than the maximum allowable
limit.
The analysis showed that the traffic noise impacts 25-40% of
the population of Bishkek negatively, even when its level is not
above the maximum allowable limit. In recent years, the noise level
has not decreased; on the contrary, it is growing gradually. From 40
to 70% of the population of Bishkek live under the conditions of
acoustic discomfort.
It is necessary to create buffer
zones with 3-row plantations. The best protection from noise
is noise-suppressing 15-meter wide shelter belts of coniferous
species (thuya, juniper) and of deciduous species (lime, mulberry)
as well as of creeping plants. Plane-trees,
hornbeams, and other plants with rough leaves are fit for dust
protection.
