录音棚项目甲方筛选设计公司时，往往要求提供以往案例。案例材料通常以 Project Photo 为主——外观、Interior Finish、Equipment Installation 状态等视觉信息。Photo 可直观呈现建成后的 Space Morphology，但仅凭 Photo 无法判断项目的 Technical Performance Level、Implementation Process 是否规范以及 Final Delivery 是否达标。

以下按 Project Purpose、Service Scope、Team Role、Critical Difficulty、Implementation & Commissioning Process、Delivery Time、Actual Usage 七个维度逐项说明核实内容。

一、Project Purpose：案例用途与当前项目匹配性

录音棚按用途分四类——Music Recording、Voice Recording（Broadcast/Voice-over）、Teaching & Training、Mixed Purpose。不同用途的 Design Standard 和 Technical Focus 差异显著。

Music Recording Studio：关注 Recording Room Acoustic Character 和 Multi-channel Synchronized Recording Capability。选型需结合 Sound Source、Distance、Polar Pattern、Self-Noise、Max SPL 和 Room Condition。

Voice Recording Studio：侧重 Low Noise Environment 和 Single/Dual-channel Recording Precision。偏干语音或配音空间参考 Mid-frequency RT 约 0.2—0.4s，Music Recording Space 可能保留 RT 约 0.3—0.6s 或更长 Variable Decay——均为 Preliminary Reference，正式比较需看 Room Volume、Frequency Band 和 Measurement Condition（ISO 3382-2:2008）。

Teaching & Training Studio：需兼顾 Multi-user Simultaneous Operation 和 Equipment Accessibility。

Mixed Purpose Studio：用途叠加推高 Design Complexity。先确认 Primary Purpose，再判断 Secondary Purpose 是否可兼顾。

Project Scale 同样影响 Design Difficulty。4-person Voice Studio vs 20-person Simultaneous Recording Space：不能只看 Occupancy 和 Floor Area，还需核实 Input Channel Count、Headphone Monitoring Distribution、Control Room、Isolation Booth、MEP Condition 和 Acoustic Target。案例与当前项目越接近，Reference Value 越高。

二、Service Scope：案例中 Design Company 实际负责范围

录音棚项目通常涉及 Architectural Acoustics、HVAC Noise Control、Power Supply Interface、Audio System 和 Cable Routing 等专业内容。核实时需看 Design Company 在案例中实际负责了哪些部分——单一专业 vs 跨专业 Design & Coordination。不能因为案例整体建成，就默认 Display Party 完成全部工作。

Design Coverage：Acoustic Design only / Audio System only / Cross-discipline Design & Coordination——以 Contract 和 Project Record 为准

Construction Support & On-site Guidance：是否提供 On-site/Remote Technical Support、参与哪些 Critical Process Milestone、发现 Deviation 后由谁提出和跟踪 Rectification。Design Quality 取决于图纸 + 施工阶段持续介入

Equipment Selection & Procurement Support：Selection Advice only / Full Participation（Selection → Procurement → Installation → Commissioning）。核实参与深度，预判后续 Service Mode

Post-delivery Service：Technical Support、Equipment Maintenance Guidance、System Adjustment 和 Necessary Re-measurement 是否包含。Room Layout / Material / Equipment / HVAC / Usage Condition 变化或 Abnormal Noise / Acoustic Variation 出现时按需 Re-measurement；是否 Periodic Re-measurement 取决于 Project Purpose、O&M Protocol 和 Contract

三、Team Role：各专业团队 Responsibility Division 与 Collaboration

录音棚项目实施涉及多个 Professional Team，各团队 Role Division 和 Collaboration Relationship 是核实重点。

Client Team：Requirement Provider / Construction Condition Provider / Acceptance Party。核实 Industry Background（Broadcast Station / University / Government Agency）和 Project Experience，判断其对 Design Requirement 的 Understanding Depth 和 Acceptance Standard 的 Mastery Level

Design Team：核实 Acoustic、Building MEP、Specialized Construction 和 Audio System Capability 分别由哪些 Personnel 或 Partner 承担。External Consultant 不天然 Sub-standard，但如果只负责 Phase-specific Drawing / Advice、无 Critical Milestone Confirmation Authority、无 Construction Change Review、不承担 Commissioning Rectification Support——Project Responsibility 易被 Fragmented

Construction Team：Floating Floor Vibration Isolation Pad Laying Precision、Acoustic Wall Sealing Treatment、Absorption Material Installation Position 和 Fixing Method。核实是否有 Recording Studio 或 Acoustic Engineering Construction Experience

Third-party Testing Body：如案例有 Third-party Report，应核对 Organization Capability / Required Qualification、Testing Method、Equipment Calibration、Room & AC Status、Frequency Range、Raw Data 和 Judgment Basis。是否必须由 Third-party 出具取决于 Project Applicable Regulation 和 Contract

四、Critical Difficulty：Technical Issue 发现与解决过程

每个录音棚项目有其特有的 Technical Difficulty。解决过程是考察 Design Company Technical Capability 的核心依据。

Building Condition Constraint：Ceiling Height Insufficient → Floating Floor & Suspended Ceiling Space Limited；External Wall Sound Insulation Insufficient；HVAC Duct Routing Fixed & Unmodifiable。核实 Constraint Condition 和 Response Scheme

Noise Source Treatment：Traffic Noise / Equipment Vibration / Adjacent Room Activity Noise。核实 Noise Control Measure 及 Effect——通过 Measured Data（而非 Photo）判断

Acoustic Target Deviation & Rectification：实测结果与 Target 是否一致、Non-conforming Item 如何 Diagnose / Rectify / Re-measure。能说明 LF / RT / Noise / System Issue 的发现与处理过程，比只展示 Success Photo 更能体现 Capability。对方不能提供 Record 时标注 "To Be Verified"，不直接推断 Project Quality 有问题

System Integration Issue：Signal Matching / Clock Sync / Gain Structure。核实 Equipment Compatibility Issue 及处理方式

五、Implementation & Commissioning Process：Photo 最无法替代的核实内容

从 Construction 到 Commissioning 的完整 Process Record，是 Case Verification 中 Information Density 最高、Photo 最无法替代的部分。

Construction Process Record：Floating Floor Construction Inspection / Acoustic Wall Pre-closure Inspection / Absorption Material Installation Inspection / Equipment Installation Inspection。Record 应由 Written Log / Checklist / Test Data / Necessary Photo 共同构成

Sound Insulation Test：核实 Testing Method、Project Phase 和 Room Status。Phase Test 尽早发现 Door/Window/Seal/Penetration Issue；Final Test 确认 Delivery Target（ISO 16283-1:2014）。Report 应记录 Door/Window/MEP/Furniture/Equipment Status，保留 Frequency Band Data + Single-value Result

Acoustic Target Test：RT / Frequency Response / Background Noise。核实 Report 是否提供 Per-band / Per-measurement-point Data，分别记录 AC / Door/Window / Furniture / Equipment / Room Occupancy Status

System Commissioning Record：Signal Path Check / Gain Structure Setting / Monitoring Calibration / Inter-device Communication Confirmation（AVIXA Systems Performance Verification Standard）。无 Commissioning Record 时仅凭 Photo 中 Equipment Connection Status 无法判断 System 是否正常工作

六、Delivery Time：常被忽视但对 Project Plan 有直接影响

Design Cycle：Requirement Confirmation → Scheme & Detail Design 的实际 Start/End Date、Deliverables 和 Change Count。中小型项目约 4—8 weeks（沟通示例）；复杂项目更长。Cycle Length 本身不证明 Quality，需结合 Deliverable Depth 和 Resource Input 判断

Construction Cycle：中小型项目约 4—8 weeks；涉及 Structural Modification / Concrete Curing / Multi-room / MEP Relocation / Phased Construction 时更长。核实各 Critical Process、Waiting Condition、Change 和 Rectification 的实际 Record

Commissioning & Acceptance Cycle：约 1—2 weeks 或 Phased Arrangement，无统一 Duration。调试时间短时应核实 Actual Test Item、Personnel Input 和是否发生 Rectification

Overall Delivery Time：Design Start → Formal Delivery 的 Total Duration 应在 Case 中明确标注。核实是否 Delay 及 Delay Reason

七、Actual Usage：建成后的真实效果判断依据

此信息通常需向 Case 的 Client 获取，Design Company 自身 Description 可能存在 Selective Presentation。

Usage Frequency & Scenario：是否按 Expected Purpose 使用。Usage Rate Low 可能来自 Requirement Change / Management Arrangement / Personnel Shortage / Technical Issue，不能单凭 Low Usage Rate 判断 Design Failure

User Feedback：Recording Quality / Monitoring Environment / Operation Convenience / Equipment Reliability。User Feedback 比 Photo 更能反映 Real Effect

Acoustic & System Status：使用一段时间后是否出现 Abnormal Noise / Equipment Fault / Space/Material Change。合格 Fixed Construction 不会因 Normal Use 必然 Significant Degradation；Re-measurement 取决于 Purpose / Change / Abnormality / O&M Protocol

Post-construction Modification：增加 Equipment / 修改 Layout / 更新 Acoustic Treatment。核实 Modification Record 和 Reason，判断 Original Design 是否充分考虑 Expansion Requirement

八、Photo Limitation：能呈现 vs 无法呈现的信息

Effect Drawing vs Real-scene Photo：前者反映 Design Intent，后者反映 Built Status。仅 Effect Drawing 无 Real-scene Photo 的 Case，Reference Value 受限。

Equipment Photo vs System Photo：仅 Equipment Appearance 无法判断 Signal Connection Correctness / System Commissioning Status / Per-channel Normal Operation。应要求提供 System Commissioning Record 或 Measured Data 作为 Photo Supplement。
