Traffic noise road and rail
Plan approval procedure, new construction or substantial modification of roads, noise remediation, noise protection window programs, dimensioning of active and passive noise protection measures.
More about this
More than 75% of the population in Germany feels annoyed by traffic noise, and quite a few are exposed to levels that are hazardous to health. This makes noise precautions in new planning and noise remediation in highly polluted existing areas all the more important.
We offer you the following services:
- Acoustic investigations within the scope of new road construction or expansion, development plans and noise remediation programs
- Calculation of road and rail traffic noise according to 16th BImSchV (Schall-03), RLS-90 and the environmental noise directive
- Conception of active noise protection measures with regard to effectiveness and economic efficiency (cost-benefit analysis)
- Dimensioning of passive noise protection measures against traffic noise
- Sound level measurements
Urban planning
Expert noise reports for building development plans, taking into account all relevant noise sources according to DIN 18005, noise allotment according to DIN 45691, building noise protection, e.g. according to DIN 4109.
More about this
DIN 18005-1 Noise protection in urban development provides information on the consideration of noise protection in urban development planning. If necessary, noise protection measures are to be determined.
We offer the following services:
- Calculation of noise immissions from all relevant noise sources;
- Conception of noise protection measures (active/passive);
- Noise quota allocation according to DIN 45691 for commercial and industrial sites, if necessary;
- Support in planning optimisation, urban development competitions and in determining the development plan.
Industrial noise
Expert noise reports according to TA Lärm for building permits for new constructions, expansions or modification of industrial facilities. Design of sound insulation concepts.
More about this
For the operation of commercial and industrial plants, the requirements of TA Lärm apply. As a rule, the granting of a building or operating permit requires appropriate proof by means of a measurement or a calculated forecast.
- Expert opinions on existing buildings, new buildings, alterations or extensions of plants and facilities according to TA Lärm by means of computational prognosis;
- Sound level measurements of existing plants;
- Draft of sound insulation concepts for compliance with sound engineering requirements;
- Sound-engineering optimisation of building designs and operating procedures.
Sports and leisure noise
Expert noise reports according to the Sports Facilities Noise Protection Ordinance (18. BImSchV) and the Leisure Time Noise Directive for existing, new or modified sports and leisure facilities and events.
More about this
The planning and operation of sports and leisure facilities has a high potential for conflict with the neighbourhood. The facilities are mainly used during the noise-sensitive periods, the evening hours and at weekends. The noise that can be expected of residents is regulated in the Sports Facilities Noise Protection Ordinance (18. BImSchV) and the Leisure Noise Directive of the countries.
- Sound engineering consulting for the planning of sports and leisure facilities;
- Sound engineering expertises on the existence, modification, new construction or expansion of sports and leisure facilities in accordance with the Sports Facilities Noise Protection Ordinance or the Leisure Noise Directive;
- Drafting of sound insulation concepts;
- Noise level measurements at existing facilities or at events.
Aircraft noise
Airfields, gliding, helicopter and landing sites, definition of noise abatement measures, control of noise pollution.
More about this
Along with road traffic noise, aircraft noise is one of the most pressing noise problems in Germany. Although aircraft manufacturers and airlines have significantly reduced noise emissions from aircraft in recent years, 6% of the German population feels disturbed by aircraft noise. This is also related to the constantly increasing number of flights. People who live in the immediate vicinity of an airport must be given special protection.
We offer you the following services:
- Noise expertises on commercial airports, gliding airfields, helicopter bases and landing fields;
- Definition of noise protection areas according to the law on protection against aircraft noise (FluLärmG);
- Determination and control of noise pollution by measuring and calculating flight routes (DES, radar tracks);
- Definition of measures for noise reduction and passive noise protection.
Noise mapping | Noise action planning according to the EU Environmental Noise Directive
Calculation according to European and national guidelines, statistics on people affected by noise, concepts for measures and support concerning public participation for municipalities and cities.
More about this
The federal states and local authorities in Germany are obliged to draw up or update a noise action plan every 5 years. The aim is to identify areas particularly affected by noise and to reduce their noise. Quiet areas are to be protected from an increase in noise. The procedure requires the participation of the population in the preparation of the noise action plans.
We offer the following services:
- Calculation of noise exposure and presentation of polluted areas (noise mapping according to European directives, statistics of affected people);
- Advice and support in the preparation of noise action plans;
- Determination of economic costs/benefits;
- Participation in public participation for municipalities and cities;
- RLS-90 calculations for building authorities.
Sound level measurements
Measurement of road and rail traffic noise, industrial noise, construction noise, sports and leisure noise as well as noise exposure at the workplace. Execution of short or long term measurements.
More about this
Accurate information on the actual noise pollution can be obtained by measuring the noise effects near the source or at the places of immission. Measurements are performed with sound level meters of accuracy class 1 according to IEC 61672:2002. The measured values obtained can be used directly for acoustic verification. By recalculating the sound power level of the measured source, measured values can also be used in prognosis calculations, e.g. in case of operational changes.
We offer the following services:
- Measurements of traffic, industrial, construction, sports and leisure noise to prove compliance with immission control regulations;
- In-situ measurements of machines and equipment to determine the sound power level (for further use in computational forecasts, among other things);
- Performance of short-term (up to 1 day) and long-term sound level measurements (over several days).
