Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation
	The accompanying interim condensed consolidated financial statements of Natus Medical Incorporated (“Natus,” “we,” “us,” “our,” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accounting policies followed in the preparation of the interim condensed consolidated financial statements are consistent in all material respects with those presented in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	Interim financial reports are prepared in accordance with the rules and regulations of the Securities and Exchange Commission; accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. The interim financial information is unaudited, and except for the prior period correction of errors disclosed below, reflects all normal adjustments that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, and cash flows for the interim periods presented. The consolidated balance sheet as of December 31, 2014 was derived from audited financial statements, but does not include all disclosures required by GAAP. The accompanying financial statements should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. We have made certain reclassifications to the prior period to conform to current period presentation.
	Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The Company is currently evaluating the impact of ASU 2014-09, which is effective for the Company in our fiscal year ending December 31, 2017.

Business Combinations [Abstract]
Business Combinations	Business Combinations
	Global Neuro-Diagnostics
	The Company acquired Global Neuro-Diagnostics ("GND") through an equity purchase on January 23, 2015. GND's service offers patients a more convenient way to complete routine EEG and video EEG testing which can be performed at the home, hospital or physician's office. The service also provides comprehensive reporting and support to the physician. The cash consideration for GND was $11.4 million. The purchase agreement also included an earn-out condition which the Company estimates to be $3.3 million. This earn-out is contingent upon GND achieving certain revenue milestones from 2015 to 2017.
	Valuing intangible assets required us to make significant estimates that will be adjusted in the future; consequently, the purchase price allocation is considered preliminary. Final determination of the value of intangible assets is expected during the second quarter of 2015 and will result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill. Pro forma financial information for the GND acquisition is not presented as it is not considered material.
	NicView
	On January 2, 2015, the Company purchased the assets of NicView for cash consideration of $1.1 million. NicView provides streaming video for families with babies in the neonatal intensive care unit.
	Hearing Screening as a Service
	In the first quarter of 2014, the Company entered into two asset purchase agreements for companies in the newborn hearing screening services market for cash consideration of $2.6 million. The purchase agreements also included an earn-out condition which is contingent upon annual revenue growth through 2016. This earn-out condition is currently estimated at $0.8 million. Both acquisitions support the Company’s objective to enter this market that complements our newborn hearing screening device business. This hearing screening services business operates under the name Peloton.

	We provide a warranty on all medical device products that is generally one year in length. We also sell extended service agreements on our medical device products that are generally over one year in length. Service for domestic customers is provided by Company-owned service centers that perform all service, repair, and calibration services. Service for international customers is provided by a combination of Company-owned facilities and vendors on a contract basis.
	We have accrued a warranty reserve, included in accrued liabilities on the accompanying condensed consolidated balance sheets, for the expected future costs of servicing products during the initial warranty period. We base the liability on actual warranty costs incurred to service those products. Additions to the reserve are based on a combination of factors including the percentage of service department labor applied to warranty repairs, as well as actual service department costs, and other judgments, such as the degree to which the product incorporates new technology. The reserve is reduced as costs are incurred to honor existing warranty obligations.

	Provision for Income Tax Expense
	Our effective tax rate (ETR) (provision for income taxes divided by pretax income) for the three months ended March 31, 2015 and 2014 was 31.3% and 30.4%, respectively. Our year-to-date results reflect the projected fiscal year ETR, as adjusted for the impact of any discrete items. Our ETR for the three months ended March 31, 2015 includes the discrete tax impact of the forgiveness of an intercompany loan between the U.S. parent company and its Argentinian subsidiary which increased our ETR by 3.7%. The discrete item recognized during the three months ended March 31, 2014 was not material to the ETR. The decrease in our ETR excluding the impact of discrete items, is due to forecasted shifts in the geographical mix of income. Our ETR for the three months ended March 31, 2015 and 2014 differed from statutory tax rates primarily because of profits taxed in foreign jurisdictions with lower tax rates than the statutory rate.
	We recorded a net tax expense of $143,000 of unrecognized tax benefits for the three months ended March 31, 2015. Within the next twelve months, it is possible our uncertain tax benefit may change within a range of approximately zero to $800,000.Our tax returns remain open to examination as follows: U.S. Federal, 2011 through 2013, U.S. States 2010 through 2013 and significant foreign jurisdictions, 2010 through 2013.

Fair Value Measurements	Fair Value Measurements
	ASC 820 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Fair value is defined under ASC 820 as the exit price associated with the sale of an asset or transfer of a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes the following three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value:
	Level 1 - Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
	Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 - Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
	The Company does not have any financial assets or liabilities measured at fair value on a recurring basis.
	The following financial instruments are not measured at fair value on the Company’s consolidated balance sheet as of March 31, 2015 and December 31, 2014, but require disclosure of their fair values: cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities.
	In the third quarter of 2014 the Company listed its facility in Mundelein, Illinois for sale. This asset was measured at fair value less cost to sell as of September 30, 2014 based on market price and is classified as a Level 2 asset. The book value of this asset on June 30, 2014 was $3.6 million. We expensed $2.2 million during the third quarter 2014 for this impairment. As of March 31, 2015 we are carrying the asset as held for sale in other current assets on the balance sheet at a value of $1.4 million.
	The Company also has contingent consideration associated with earn-outs from acquisitions. Contingent consideration liabilities are classified as Level 3 liabilities, as the Company uses unobservable inputs to value them, which is a probability-based income approach. Subsequent changes in the fair value of contingent consideration liabilities are recorded within the Company's income statement as an operating expense.
		December 31, 2014		Additions		Payments		March 31, 2015
	Liabilities:
	Contingent consideration	$	812	$	3,319	$	—	$	4,131
	Total	$	812	$	3,319	$	—	$	4,131
	As presented in the table above, the significant unobservable inputs used in the fair value measurement of contingent consideration related to the acquisitions are annualized revenue forecasts developed by the Company’s management and the probability of achievement of those revenue forecasts. Significant increases (decreases) in these unobservable inputs in isolation would result in a significantly lower (higher) fair value measurement.

Immaterial Corrections to Prior Period Financial Statements	Immaterial Corrections to Prior Period Financial Statements
	Certain amounts previously reported in the consolidated statements of income and statements of cash flows for the three months ended March 31, 2014 have been restated to reflect the correction of an immaterial error as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. The error related to the amount of manufacturing labor and overhead applied to inventory. We believe the effects of the error are not material to our consolidated financial statements.
	A summary of the effects of the correction of this error on our consolidated financial statements for the three months ended March 31, 2014 is presented in the table below (in thousands, except per share data):

Recent Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 sets forth a new revenue recognition model that requires identifying the contract, identifying the performance obligations, determining the transaction price, allocating the transaction price to performance obligations and recognizing the revenue upon satisfaction of performance obligations. The Company is currently evaluating the impact of ASU 2014-09, which is effective for the Company in our fiscal year ending December 31, 2017.
