Restrictions on turbine noise face legislative hurdle

The committee’s charge is rather to ask a fairly narrow set of questions about a rule, Benning said, including whether it meets the intent of the legislation that enabled it, whether the rule is arbitrary, and whether its potential economic effects are adequately described. Benning said he’s satisfied the rule meets all these criteria.

Wind turbines causing problems in Scituate, Massachusetts

Acting Town Administrator Al Bangert said they agreed to shut down the turbine during the hours of 11 p.m. to 6 a.m. when the wind blows from the southwest. ...Officials said since then, complaints have dropped more than 60 percent. But there has been a financial cost as well. Bangert is forecasting a financial loss of more than $100,000 per year whenever the blades power down.

Infrasound from wind turbines is a new signal in the environment

Infrasound-aunio-group-34_2017-1_thumb FINLAND. Aunio Group Oy from Oulu has developed a device for measuring and recording infrasound produced by wind turbines. The measurement equipment can be used to produce research data for investigating the characteristics of infrasound and where it spreads, and to analyze any health problems it may cause. The infrasound produced by wind turbines differs from infra-sounds occurring in nature; according to measurements the infrasound produced by wind turbines is a clear signal - distinguishable from ambient noise in the environment. This paper describes the method of evaluating the Anuio Group's device and the results. The full paper can be accessed by clicking the links on this page.

Inspectors find turbine breaches noise limits

It has been revealed that a wind turbine which has caused years of "anguish and distress" for residents in Castlewellan has breached required noise limits at a nearby residential property. ...A major factor that has been troubling residents in the area since the turbine was erected is the noise emitted.

Neighbours at odds over noisy wind farm

Huffman told commissioners the problems were worst when wind speeds were low, particularly between 6 metres per second and 10m per second. She backed the city council's position, that there should be an 8m per second threshold before the turbines kick in at night. She also said subjective assessment was a legitimate way to monitor noise.

Status: Aramini-Krogh project to evaluate Health Canada Wind Turbine Noise and Health Study

Stats_canada_health_canada_raw_data_project_update_july_2017_thumb In November 2014, Health Canada released the results of its $2.1 million “Wind Turbine Noise and Health Study.” Despite public anouncements from Health Canada that the raw data originating from the Study would be made available, the data continues to be inaccessible making it impossible to validate the conclusions drawn by Health Canada researchers. For example, HC found high levels of annoyance but concluded no association to turbine noise.

Wind turbine syndrome: infrasound and fury

The question of whether wind turbines are physically capable of producing the adverse reactions claimed is unresolved. However, it is now scientifically demonstrated by Swedish researchers that amplitude-modulated low-frequency wind turbine noise can directly cause sleep disturbance, even in young fit people taking part in its research study.

Panel Ices Wind Rules Until October

It's all likely to prove academic, since LCAR is almost certain to vote down the rules sometime after leaf-peeping season. At that point, the PSB would have to resume work on a new set of rules. Given the fact that the board and the Scott administration take a dim view of ridgeline wind and most legislators are in favor of renewable energy including wind, it's going to be very tricky to find a set of rules acceptable to all parties. ​

A possible criterion for wind farms

Schomer_2017-a_possible_criterion_for_wind_farms_thumb The purpose of this paper is to explain and evaluate the metric by which the community response to wind turbine noise is gauged and the limits appropriate to that response function. Chapter II deals with selection of the metric, and Chapter III presents the data and methods used to establish criteria and a criterion, based on the metric selected. The abstract of the paper is provided below. The full paper can be accessed by clicking the links on this page.

Wind noise should be overseen by state, not developer

Permit enforcement is a concern raised at nearly every public hearing for renewable energy projects. People want the government to protect them if and when a company violates the terms of its operating permit. It's hard to trust that the government will do that when so much of the monitoring process is in the hands of the company being monitored or its agents.
